GNSS covers all the different satellite systems in use worldwide, such as GPS (USA), GLONASS

(Russia), Galileo (Europe), Beidou (China). RTK (Real time kinematic) RTK (Real-Time Kinematic) positioning is a method used by an RTK-enabled GNSS receiver (called a Rover, in this case the RD8200SG) to obtain extremely precise positions by using data from an RTK base station that is transmitted over the internet (NTRIP). NTRIP NTRIP stands for Networked Transport of RTCM via Internet Protocol. The NTRIP protocol enables the mobile GNSS receiver (RD8200SG) to access data from the RTK base station over the internet to achieve high accuracy. NTRIP can be built in the structure of a mapping app or it can be a separate mobile app. 2023 Radiodetection Ltd 20 5.2 Pairing Bluetooth Modules Pairing Bluetooth Modules 4.

ON turns on the magnetic heading compensation for the GNSS position (default state) OFF turns off the magnetic heading compensation for the GNSS position CHECK displays the current heading value under the bar graph (figure 8). This is useful to compare heading accuracy with another physical or digital device. The error is also shown in the bottom right (figure 8). RESET selecting reset and then YES will reset the calibration of the magnetic compass. Over time the accuracy may degrade, or environmental/location factors may impact the accuracy and require a re-calibration. Once selected, the user will need to slowly spin the locator in a circle whilst 50 reference points are taken. Whilst this process is occurring the number of points taken is displayed in the bottom right of the display (figure 7a and 7b) EXIT exits from this part of the 1. In the RD8200SG settings, navigate to: INFO >

MAG_H > RESET > YES 2. Then press the button 4 times to return to the main screen. The RD8200SG will now be in Magnetic Compass RESET mode. (Reset mode means the magnetic compass calibration process has begun). 3. Slowly rotate the locator through 360 degrees whilst maintaining a vertical orientation, using the spirit level bubble (within 5 deg from vertical). You will see the two highlighted numbers in figure 7a and 7b increase together as more valid calibration measurements are taken. These two numbers will always be the same in RESET mode. Keep rotating until the numbers reach at least 50 valid measurements. 4. Once 50 valid measurements are obtained, the RD8200SG will automatically switch into the CHECK mode. The purpose of check mode is to evaluate calibration quality. In this mode the two highlighted numbers (figure 8) will be different the top number represents magnetic heading (like a conventional compass with north being 0 degrees) and the bottom number represents the calibration percentage error. 5. Check mode can be accessed at any time, without having to complete RESET mode, through:

Figure 7a Figure 7b North Figure 8 2023 Radiodetection Ltd 30 Locating cables and pipes This section introduces the principals and techniques of locating buried cable and pipe utilities with the RD8200SG system. For more information on the theory of cable and pipe location, refer to The theory of buried cable and pipe location which is available to download from www.radiodetection.com 6.1 Frequencies Contact your distributor operators. local Radiodetection sales office or these in if you require help identifying The RD8200SG locator supports a range of active and passive frequencies. It also supports 5 additional user definable frequencies in the range of 50Hz to 999Hz. Refer to the RD Manager Online operation manual for more information on how to set up custom frequencies. For a complete list of supported frequencies, refer to the RD8200SG Locator Specification datasheet. Active frequencies Passive frequencies Passive frequency detection takes advantage of signals that may be present on buried metallic conductors. The RD8200SG types of passive frequencies: Power, Radio, CPS and CATV signals. locator supports four You can detect these frequencies without the aid of a transmitter if they are present on the utility you are surveying. Power Filters RD8200SG locators allow you to take advantage of the harmonic signals found on power networks. When strong or interfering power signals are present, accurate tracing of a target cable can be challenging. Power Filters allow you to establish if a single large power signal comes from one source or from the presence of multiple cables. The different harmonic characteristics of the detected lines can then be used to trace and mark their route. Once in Power Mode, press the key to switch out of Radiodetections sensitive Power Mode and scroll through the five individual Power Filters. The use of an individual Power Filter harmonic can also allow you to locate power lines in situations where the total signal would otherwise be too large. Custom frequencies You can set up to 5 additional; custom frequencies in your locator for use on specific networks. Frequencies in the range of 50Hz to 999Hz can be set using RD Manager Online. CAUTION: When using custom frequencies in the range of 692Hz to 704Hz or 981Hz to 993Hz the locator audio may interfere with the locator and must be turned off. NOTE: Some frequencies (e.g. 440Hz) may be reserved for specific applications in your country and permission from the relevant operator(s) may be required for their use. Active frequencies are applied to a buried conductor using the transmitter. The transmitter can apply a signal using three methods:

Direct Connection In Direct Connection, you connect the transmitter output directly to the utility. The transmitter will then apply a discrete signal which you can locate using the locator. This is the preferred method of applying a transmitter signal to a utility and in the majority of applications will apply a stronger signal to the utility, which may increase the locate distance. To directly connect conductive utility:

1 Switch the transmitter off to a non-energized 2 Connect the Direct Connection lead into the transmitter accessory socket 3 Clip the red connection lead to the utility ensuring that the area around the connection is clean and that a positive connection is achieved 4 Clip the black connection lead as far away as possible and at 90 to the ground stake or suitable ground point nearby ensuring is achieved that a positive connection 5 Switch the transmitter On 6 The display will show the Direct Connection lead connected icon Figure 6.1 Direct Connection lead icon For more information about other signal connection accessories, refer to Section 12. WARNING! Direct Connection to live conductors is POTENTIALLY LETHAL. Direct connections live conductors should be attempted by fully qualified personnel only using the relevant products that allow connections to energized lines. to 2023 Radiodetection Ltd 31 WARNING! The transmitter is capable of outputting potentially lethal voltages. Take care when handling the terminals, connection leads and ground stake, notify other technicians working on the line of the hazard and guard exposed conductors to prevent accidental contact. WARNING! Ensure the TX transmitter is switched OFF before making a connection and before disconnection of the direct connection lead to a service. Induction In this mode of operation, the transmitter is placed on the ground over or near the survey area. If a Direct Connection lead or signal clamp is not plugged into the transmitter, it will automatically go into induction mode. In this mode, only frequencies applicable for induction mode will be made available as the key is pressed. Once activated the transmitter will induce the signal indiscriminately to any nearby buried conductors. Please note that these signals will also be airborne and it is advisable to keep the distance between the transmitter and locator at least 10m / 30 this distance may need to be increased, particularly if depth measurements are taken. Signal clamp An optional signal clamp can be connected to the transmitter and clamped around a cable or pipe to apply the transmitter signal. This method of applying the transmitter signal is particularly useful on insulated live wires and removes the need to disconnect the supply to the cable. Clamps are available up to 8.5 / 215mm in diameter. WARNING! Do not clamp around uninsulated live conductors problem-solving by technically competent technicians, a range of frequencies may be provided. Typical examples of these and reasons for their use are illustrated below. 512Hz Figure 6.2 512Hz active signal This low frequency is most useful for line tracing and identification over long distances. It does not couple easily to unwanted lines however it is too low for induction, and it falls within the band of power frequency harmonic interference. 8kHz Figure 6.3 8kHz active signal This medium frequency is the most useful general-

purpose signal, high enough for induction, outside the power frequency interference band, and with limited coupling to wanted lines however it may not be high enough to impose a strong signal on small diameter line like telecom cables. 33kHz Figure 6.4 33kHz active signal This higher frequency is easily applied by induction to most lines, so is very useful for initial search. It travels on small diameter line however it couples more easily to unwanted lines, and loses its strength over shorter distances than lower frequencies. WARNING! Before applying or removing the clamp around a power cable, ensure that the clamp is connected to the transmitter at all times. 100kHz and Over 6.2 Choice of frequency for active location The choice of signal frequency is an important factor for effective tracing and identification of buried lines, and there is no single frequency that covers all conditions. For simple instruments to be used by relatively non-technical personnel, there is no option but to make a compromise, and choose a single frequency high enough to give good performance in the induction mode, but not so high that it will couple too easily into unwanted lines. Active signals between 8kHz and 33kHz are commonly used for these applications. For more comprehensive equipment for Figure 6.5 100kHz active signal This very high frequency range deals with the difficult cases induction onto small diameter lines in dry sandy soil, and short lengths of cable. It is very easy to apply by induction however it couples very easily to unwanted lines, and does not travel far. 512 Hz operation Due to mobile phone interference, active frequencies below 500 Hz can be unsatisfactory or unusable. The RD8200SG will be perfectly useable at 512 Hz although an experienced customer might notice that they need to set a higher power output on the TX. 2023 Radiodetection Ltd 32 information see Section 5.1, visit For more the Knowledge Base section in support.radiodetection.com or refer to the application note The theory of buried pipe location, which is available as a free download from https://www.radiodetection.com/en-gb/cable-and-pipe-

You can change your transmitters output frequency manually using your transmitters keypad or automatically using iLOC (Bluetooth transmitters only). To manually select a transmitter output frequency:

Peak+ mode Peak+ mode combines the accuracy of the Peak bargraph with a choice of Guidance or Null directional arrows. Guidance arrows provide visual indication of the direction to the target utility, and are designed to get you close to the Peak position faster, before using the Peak bargraph to pinpoint the target utility, Using Null arrows allow you to check for distortion before marking a point, and should be used when accurate locate measurements are required. To change frequencies using iLOC, refer to Section 11. Switching between arrow types:

NOTE: Some frequencies require that you connect an accessory, for example an A-Frame, before the frequency is available. 6.3 Antenna modes The RD8200SG system supports five antenna modes, exclusively dedicated to locating cable and pipes, and to suit your particular application or the local environment. These are:

Peak mode Peak+ mode Guidance mode Broad Peak mode Null mode Peak mode Peak mode provides the most sensitive and accurate mode for location and depth measurement. It provides a When in Peak+ mode, press and hold the between Guidance and Null arrow types. key to toggle You can also select the default arrow type in the locator menu:

Use the proportional arrows to guide the locator along the path of the target cable or pipe. To accurately locate the center point of the target utility, for example to mark a point or take a survey measurement, use the Peak bargraph to pinpoint the Peak position. 2023 Radiodetection Ltd 33 When using Null arrows:

Use the arrow heads to place the locator above the NULL point. If the Peak response is not at a maximum, then this is evidence of a distorted field. If the Peak response is at its maximum level where the Null point is located, then there is no or very limited distortion present. In Peak+ mode the following indicators are displayed by the LCD:

Right and left arrows Signal strength Compass Current Depth To select Peak+ mode:

Depth Current Signal strength Compass To select Broad Peak mode:

1 Press the key until the Broad Peak mode icon is displayed on the LCD. Null mode Null mode is used to verify a locate signal in environments with limited or no interference or distortion. Null mode gives a null response when it is directly over the line. In Null mode the following indicators are displayed by the LCD:

1 Press the key until the Peak+ mode icon is Signal strength. displayed on the LCD Guidance mode Guidance mode offers good performance in distorted fields and provides three indicators to guide the user towards the target line. The Left and Right Proportional Arrows become shorter as the locator approaches the target, and the Target Position Needle will move towards its central position. The Signal Strength reading will also reach its maximum value when the locator is positioned above the target. Any deviation from all three indicators showing the target position in the same location could signal the presence of a distorted field. In Guidance mode the following indicators are displayed:

Proportional left and right arrows Target Position Needle Signal strength Gain Compass Current Depth To select Guidance mode:

1 Press the key until the Guidance mode icon is displayed on the LCD Broad Peak mode In Broad Peak mode, the RD8200SG locator uses a single antenna to detect with higher sensitivity over a wider area than Peak mode. This is particularly useful for locating deep utilities quickly and indiscriminately. In Broad Peak mode the following indicators are displayed by the LCD:

Compass. Right and left arrows. To select null mode:

1 Press the key until the null mode icon is displayed on the LCD The sharp, null response can be easier to use than the Peak response but is vulnerable to interference and should not be used for locating, except in areas where there is no interference present. Guidance Mode offers improved performance in such conditions while Peak+ mode can combine the Peak bargraph with Guidance arrows to combine fast and accurate locate tools. 6.4 Compass The LCD compass provides a visual indication of the direction of the target cable, pipe or sonde. The compass is available for all frequencies apart from Power, Radio and Passive. 6.5 Trace Line tracing can be accelerated by switching the locator to Guidance mode. Move the locator left and right while walking along the path of the line to place the target position Needle directly over the line. As you move the locator over the line, the left and right arrows (and an accompanying tone) will indicate if the target line is to the left or right of the locator. 6.6 Pinpoint Locating a target line in Peak, or Peak+, mode accurately defines the position of a target line after it has been traced 2023 Radiodetection Ltd 34 and its position is approximately known. Start with medium output power from the transmitter, medium frequency on the transmitter and locator, and Peak or show an error to the same side. True line position will be close to the Peak position. The line lies half the distance to the other side of the Peak position as the distance between the Peak and the Null positions. Figure 5.2: Pinpointing a target line Figure 5.3: Pinpointing with Peak and Null indicators Peak+ mode on the locator. Set the locator sensitivity to approximately 50% by pressing the key or NOTE: it may be necessary to adjust the sensitivity level throughout the pinpointing to keep the bar graph on scale. 1 With the antenna perpendicular to the line, make the point of line. Define the traverses across maximum response. 2 Without moving the locator, turn it round as if it is on a pivot. Stop at the point of maximum response. 3 Hold the locator vertical with the antenna just above the ground and move the locator from side to side across the line. Stop at the point of maximum response. 4 With the end of the antenna close to the ground, repeat steps 2 and 3. 5 Mark the position and direction of the line. Repeat the steps of the procedure to increase pinpoint accuracy. If using Peak+ mode, switch to null arrows by pressing and holding the key. Alternatively switch to Null antenna mode. Move the locator to find the Null position. If the position of the Peak and the Null pinpoints correspond, it can be assumed that the pinpoint is accurate. The pinpoint is not precise if the marks do not correspond, but both marks will 6.7 Sweep and search There are a number of techniques available for locating unknown lines in an area. Using these techniques is particularly important before conducting any excavation work to help ensure that buried lines are not damaged. Passive sweep A passive sweep is used to locate Power, Radio, CATV or CPS signals that may radiate from buried conductors. To perform a passive sweep:

1 Press the key to select the passive frequency you wish to locate. You can select from the following passive frequencies:

Power Radio CATV (Cable TV) CPS (Cathodic Protection System) PASSIV (simultaneously detects Power and Radio signals where present) 2 Adjust the sensitivity the sensitivity to keep the bar graph on scale when there is a response. to maximum; reduce 3 Traverse the area in a grid search, at a steady walk, and hold the locator comfortably with the antenna in line with the direction of movement and at right angles to any lines that may be crossed. Figure 6.4: Passive sweep Stop when the locator response rises to indicate the presence of a line. Pinpoint the line and mark its position. Trace the line out of the area being searched. Resume grid search in the area. In some areas there may be a confusing amount of 50 /

60Hz power signals. Lift the locator 50mm / 2 from the key to ground and continue the sweep, or use the 2023 Radiodetection Ltd 35 switch from Power mode and use Power Filters to discriminate individual lines. highest signal which indicates that the transmitter is also directly above the line(s). Switch the locator to Radio Mode. Increase sensitivity to maximum and repeat the above grid search procedure over the area. Pinpoint, mark, and trace out any lines that are located. In most, but not all areas, radio mode will locate lines that do not radiate power signals and a grid search should be made in both power and radio modes or in Passive Avoidance mode. Mark the ground at the point of each Peak signal detected with the locator. Repeat the search along any other possible paths of lines. Once the positions of any lines the have been marked, transmitter over and along each line in turn, and trace the line out of the search area. reverse positions, place 6.8 Nulling Out Inductive search An inductive search procedure is a more certain technique for locating unknown lines. This type of search requires a transmitter and locator and two people. This type of search is referred to as a two person sweep. Before starting the sweep, define the area of search and the probable direction of lines crossing the area. Ensure the transmitter is switched on in induction mode. Sometimes it is possible for some utilities to be masked by other utilities and this can happen when one or more utilities are in close proximity to each other or when stronger signals may radiate. In certain applications and congested areas, the Nulling technique allows operators to eliminate the induction signal directly beneath the transmitter but at the same time induces the transmitter signal onto other nearby utilities that previously have not been able to be located Figure 6.5: Inductive search The first person operates the transmitter and the second person operates the locator. The transmitter induces a signal onto lines as it passes over them and the lines are then detected with the locator at a suitable distance away from the transmitter (around 15 meters / 50 feet although this will depend upon the level of induction power used.) Hold the transmitter with its length aligned with the assumed direction of any lines. The second person holds the locator at the start of the area to be searched and with the locator antennas at right angles to the probable direction of the buried lines. Set the locator sensitivity level as high as possible without the locator picking up any airborne signals directly from the transmitter. When the transmitter and locator are in line both operators start to move forward in parallel. The operator with the locator sweeps it backwards and forwards, keeping the locator vertical, as they proceed in parallel with the transmitter. This method allows for misalignment of the transmitter, locator and buried line. The transmitter applies the strongest signal to the lines directly below it, which are then located with the locator. Move the transmitter from side to side to establish the Figure 6.6 Nulling Out effect Two persons Nulling Out technique:

1. Place the transmitter close to the services you wish to trace (a parallel sweep may be used for this) and using the locator at a distance of approximately 10m/30 from the transmitter, pinpoint the strongest signal. 2. The sensitivity on the locator is adjusted so that the bar graph response is approximately 75%

3. Release the side support arm. 4. With the locator over the centre of the signal the second operator should hold the transmitter at waist level, with the transmitter on its side release support arm pointing down. 5. The transmitter is then moved from side to side to find the Null spot between two detectable signals; the transmitter should then be lowered towards the ground keeping it in the Null spot. 6. At ground level we are ideally looking for a Null no wider than 50mm/2 (Sensitivity on the locator may need to be adjusted to achieve this). 7. With the transmitter left on the ground in the Null spot. The locator is used to check for additional signals either side of the Nulled signal. 2023 Radiodetection Ltd 36 8. Should the ground be uneven the transmitter may be turned across the line of the service provided the release support arm remains facing downwards. (this will improve the stability of the unit) One person Nulling Out technique Figure 6.7 Nulling Out - Single person sweep 1. Lay the transmitter on its side using the side support arm. 2. Sweep the area around the transmitter with the receiver at least 10m/30 from it. 3. Reposition the transmitter at 5m/15 intervals around the area and repeat step 2 4. Stop when there is a response 5. Pinpoint and mark any lines 6. Trace the lines out of the area 2023 Radiodetection Ltd 37 Depth and current readings 7.1 TruDepth The RD8200SG locator provides automatic depth of buried cables, pipes and sondes and when the locator is correctly orientated above the target line or sonde. Current readings are also displayed simultaneously if the locator is orientated correctly (feature not available in sonde or passive frequency modes). Depth and current readings are automatically displayed simultaneously, but if the locator is not correctly orientated neither reading will be displayed. Depth range and accuracy vary depending on the makeup and type of target utility (e.g. cable, pipe or sonde), its like depth and external environmental electromagnetic and interference. factors conditions ground noise, WARNING! The accuracy of depth measurement is subject to a number of factors and is meant as a guide only. Never use the depth measurement to define mechanical digging depths. Always follow local safe digging guidelines. The depth measurement is to the center of the pipe, cable or sonde. The best readings are typically detected from active signals output by a transmitter rather than from passive sources. The RD8200SG locator is capable of determining cable depth when locating some passive power signals. However passive signals on lines are less suited for measuring depth because accuracy can be compromised by interference- e.g due to the passive signal being present on more than one line. WARNING! Do not make depth measurements near bends or tees in the line. Go at least 5m (16ft) from a bend for best accuracy. TruDepth for buried conductors or sondes TruDepth and Compass It is important to note that the RD8200SG locator will only display depth and current (in applicable modes) when the locator is correctly orientated above the target line, cable or sonde. To ensure the locator is correctly orientated, use the Compass feature. When locating lines, make sure the Compass display is in the North / South orientation position. When locating sondes (see Section 13), make sure the Compass display is in the East / West orientation. Figure 7.1: Taking a depth reading To minimize signal distortion, do not apply the signal by induction. If Direct Connection or signal clamping is not possible, place the transmitter in induction at least 15m

(50ft) from the point of any depth measurements. Depth measurements may not be accurate if there is audible interference or if part of the transmitter signal has coupled to a nearby line. Confirming the Peak position coincides with a Null position indicates that the position is suitable for making a depth estimate. Figures 7.2: Depth readings Pinpoint the target line accurately with the locator Check the locator is directly over the line, the antennas are at right angles to it and the locator is vertical. Adjust the sensitivity level to bring the bar graph indication to approximately 50%

If the ground appears to radiate a strong field, perhaps near a radio station, check depth by holding the bottom of the antenna 50mm (2) above the ground and subtract this reading from the indicated depth. 7.2 Verifying depth measurements Check a suspect or critical depth reading by lifting the locator 50mm (2) above the ground and repeating the measurement. If the measured depth increases by the same amount it is a good indication that the depth reading is correct. locating When for a conductor or sonde, depth measurements should be precise to 3% if conditions are suitable. However, you may not always know if the 2023 Radiodetection Ltd 38 conditions are suitable so the following techniques should be used to check critical readings:

Check that the route of the line is straight for at least 2 meters (6 ft) to either side of the measurement point. Check that the signal response is reasonably constant over the 15-meter distance to the transmitter and make depth measurements to either side of the original point. Check that there are no adjacent lines carrying a significant signal within 1 to 2 meters (3 to 6 ft) of the target line. This is the most common source of error of depth measurements as a strong signal coupled to an adjacent line can often introduce 50% error. Make several depth measurements at points slightly displaced from the lines apparent position. The shallowest indication will be the most accurate and will also indicate the lines position most accurately. Checking depth accuracy This paragraph describes several quick and easy ways of verifying that the depth reading on the locator when used for markers or conductors and sondes is within acceptable limits. Refer to this if you are getting inaccurate depth readings from a cable or pipe for which you know the approximate depth. Inaccurate depth readings could be the result of the locator picking up a stronger signal such as another cable or pipe running in close parallel to the target pipe or cable. There are two ways of checking the calibration of the locator in the field. Both methods require the use of a transmitter:

Method 1 Method 2 1 Apply a signal to a cable or pipe of known depth. 2 Locate the cable or pipe; the locator will display depth on the LCD automatically. 3 Compare the depth reading on the locator with the actual depth. NOTE: The accuracy of depth measurement is subject to a number of factors and is meant as a guide only. Exercise caution when performing any excavation. 7.3 Current readings Identifying a utility using current measurements Measuring current value on a line helps confirm the identity of the line and may provide information about the condition of cable insulation or pipe coating. About current measurements The transmitter applies a signal or current onto a target line. The current decreases in strength as the distance from the transmitter increases. This rate of decrease depends on the type of line and on soil conditions. Regardless of the type of line and the frequency being used the rate of decrease should be regular with no sudden drops or changes. Any sudden or abrupt current change indicates that the line or its condition has changed. Place the transmitter on top of a non-metallic object, 18 /

500mm in height or more, on the ground and away from any buried lines. Switch the transmitter on in induction mode. Hold the locator with the blade horizontal and pointing transmitter and front of approximately five meters from the front of the transmitter. towards the the 1 Switch the locator on. 2 Select the same frequency as is selected on the transmitter but make sure that this frequency is in the sonde mode. 3 Move the locator from left to right and when the bargraph reading is at its Peak note the depth as indicated on the locator. Measure the distance from the base of the locator to the center of the transmitter using a tape measure. 4 Compare this reading with the depth reading on the locator. The locator can be considered accurate if the difference between the depth reading on the locator and the distance measured with the tape is less than 10%. Figure 7.3 Current readings In congested areas, where there is more than one line, the locator may sometimes detect a stronger signal from an adjacent line to which the signal has coupled or shares common grounding because it is nearer the surface. Although current measurement compensates for depth, signal response will be less as the depth increases. 2023 Radiodetection Ltd 39 The line with the highest current measurement, rather than the line giving the strongest response, is the target line to which the transmitter signal has been connected. Measuring current provides useful information about the position of bends and intersections. Measuring current after a tee will indicate the main line that pulls more current along its greater length. Signal current measurements Pinpoint the line and confirm the accuracy of the Peak pinpoint with null arrows. Check the locator is directly over the line, with the antennas at right angles to it and vertical. The locator will automatically estimate and display depth on the LCD. A signal coupled to a nearby line may distort the accuracy of the measurement. If the accuracy of the reading is suspect, sweep the area to check if other nearby lines are radiating If other signals are causing interference, it may be necessary to make the current measurement at another point along the line. the signal. to make a current Both antennas are needed measurement and locator accessory antennas such as a normal clamp or stethoscope cannot be used. Because current measurement is a function of depth, it is only available in the locating modes. It is also available with Current Direction (CD) clamps. Figure 7.7: Current readings using transmitter signa Figures 7.4 7.6 Taking current readings Applying a transmitter signal The transmitter signal can be connected, clamped or induced to the target line in the same way as the signal for line tracing is applied. WARNING! Direct Connection to live conductors is live POTENTIALLY LETHAL. Direct Connections conductors should be attempted by fully qualified personnel only using the relevant products that allow connections to energized lines. to 2023 Radiodetection Ltd 40 Locating techniques 8.1 Identifying target utilities Induction If several conductors are running in parallel, and it is not possible to connect a transmitter, each line may be located separately. Proceed as follows:

1 Perform a sweep of the area to find the position and number of conductors in the area. 2 Map the direction in which the conductors are going. To trace the lines:

1 Select induction mode on the transmitter. 2 Select the same frequency as on the locator. 3 Place the transmitter on its side and in line with a conductor 4 Ensure the conductor is directly below the transmitter 5 This will null out the signal directly below the transmitter, placing no signal on that conductor, and enable the other conductors to be located 6 Locate each conductor and mark its position 7 Move the transmitter down the route and continue locating and marking. 8 Trace each conductor out of the search area until the target can be accurately located. Unwanted signal coupling Unwanted coupling of the signal from the target line to another nearby line is one of the most common location problems. It leads either to an error in the marked position and depth of the target line or to marking the wrong line. A certain degree of coupling is unavoidable in many situations but there are ways in which a careful user can reduce coupling and increase location reliability. Avoid applying the signal by induction. The signal may be coupling to more than one line directly from the transmitter. Use the signal clamp where possible. Identify points where lines may be bonded or in close proximity to each other. Work toward these points rather than away from them. For example, if gas and water pipes are bonded within a building, apply the signal at the valves or access points in the road rather than in the building. Choose a signal application point where the line is furthest from other lines and not in a congested area When using single-ended connection, site the ground stake as far from the target line as possible and away from other buried lines Avoid using existing structures for ground connections; other buried lines may be bonded to them A bad ground connection or just laying the ground lead on the surface at right angles to the line may result in less coupling than a good ground provided long distance tracing is not required. Figures 8.1 8.4: Nulling utilities & interference from services Reduce coupling to a parallel line by using a low signal frequency where available 8.2 Signal & ground connection Return signal flowing on another line. Use a double-

ended connection to by-pass the ground return if possible Manhole covers Sometimes when locating, it is not possible to insert the ground stake into the earth, for example, when locating on 2023 Radiodetection Ltd 41 hard ground such as roads. In this case, the ground return can be made by attaching the ground lead to the metal frame of a manhole. Using lighting columns Direct Connecting to a metal, street-lamp column is almost as effective as connecting to the cable sheath itself. Normally the cable sheath is bonded to the metal column, therefore a simple connection onto the column enables the user to locate the street lighting quickly and safely without having to call out a technician from the lighting company. If the lighting column is made from concrete make the transmitter connection to the cable sheath unless the cable is earthed to the inspection doorframe. Connection to the cable sheath applies the transmitter signal for a considerable distance enabling the locator to trace cables feeding illuminated street furniture as well as other street lights. WARNING! The live cable connector is for use only by operators licensed or permitted to work on live cables. The use of a street light column as a means of applying a signal to other power cables on the same electric circuit is a possibility. The signal may be weak using this method because it may have travelled some distance back to the sub-station and out again on the other system. With the locator used on a high sensitivity setting it is often possible to locate a cable, which would otherwise have been difficult or inconvenient to energize with the transmitter signal. Finding a good ground point When using a Direct Connection, it is important to get the best possible grounding for the transmitter. This provides the lowest resistance ground path and the best output signal. If it is not possible to use the ground stake the following are examples of good alternative ground points:

Metal manhole covers Metal drainage grates Metal railings Metal fence posts 8.3 Double-ended connections Large diameter water pipes and gas distribution pipes that are laid in sections sometimes have insulated joints between the sections and can be difficult to locate using a single ended connect. This is because when using a single ended connection ground return, signals can often cause confusion by returning to the transmitter along other lines. The problem sometimes occurs when return signals appear stronger than on the target line, usually because the target line is deeper than the line carrying the return signal, or the return path may be a better electrical conductor than the target line. Applying a double-ended transmitter connection is a useful technique for positively tracing and identifying a target line in a situation such as a heavily congested industrial site, provided there are access points at each end of the line. Making a double-ended connection Connect the transmitter to an access point on the target line. The transmitter ground is connected with a long cable to another access point further along the line. A complete circuit is achieved without using ground as a current return path. The long cable should be kept as far away as possible from the expected route of the line. This method of applying the transmitter signal is ideal for positive identification of a target line. When a connection has been made to two points on the same line, the same level of current should be detectable around the circuit. The locator display should remain constant if the depth of the line does not change. Figure 8.5: Making double-ended connections 2023 Radiodetection Ltd 42 Fault-finding 9.1 About fault-finding RD8200SG locators are capable of locating cable to ground faults caused by damaged cable sheaths and can also be used to locate damage to insulation on pipelines. This process is known as Fault-Finding and uses specific fault find signals applied to the target. Fault find signals can only be applied using Direct Connection method. The A-frame accessory is used to locate cable sheath faults on power and telecom cables or insulation faults on pipelines. To use Fault-Find you will need the following equipment:

NOTE: Always connect the black connection lead to a ground stake and not a water pipe or buried cable, as these may carry the signal. Reference readings It is good practice to obtain a reference reading from the ground stake before you attempt to locate a fault on a target line. Reference readings help to provide the following information:

Severity of fault Survey interval Before taking the reference reading set up the transmitter and locator as follow:

RD8200SG locator Tx-5 or Tx-10 transmitter On the transmitter:

Accessory A-frame with connecting lead 1 Select a fault-finding frequency using the key Direct connection lead and earth stake 2 Use the or keys to increase or decrease the There are 2 types of signals that can be used for fault finding:

8K Fault Find useful for sheath faults on cables but can also be used on pipelines over shorter distances. CD Fault Find (only available on Tx-10) this low frequency signal is very useful on pipelines and particularly useful on long distance pipelines. CD can also be used for locating sheath faults on cables. 9.2 Preparation Using RD8200SG standard locating techniques locate the cable or pipe for a short distance and trace and mark its route. Remove all earth bonds from the line to be traced during the fault-finding survey. If there are any earth bonds along the path the fault find signal may direct the user to this location as this will be the preferred path for the fault find signal to leak away into the ground and may result in the fault not being located. output signal level 3 If required, you can use the BOOST setting if the fault is located on a high resistance cable or if the cable is long WARNING! By selecting 8KFF the transmitter will have the ability to output high voltages and a high voltage warning icon will appear on the transmitters LCD. On the locator:

4 Connect one end of the connection lead to the A-

frame socket 5 Connect the other end to the locator accessory socket 6 The locator will automatically recognize the A-frame and display the A-frame icon on the LCD 7 Select a fault-finding frequency using the key NOTE: If the locator and transmitter are iLOC enabled then you can remotely control the transmitter using the locator. See Section 11 for more information. Connecting the transmitter Obtaining a reference reading:

1 With the transmitter switched off connect the Direct Connection lead into the transmitter accessory socket 2 Clip the red connection lead to the cable, cable sheath or pipe ensuring that the area around the connection is clean and that a positive connection is achieved 3 Extend the black connection lead as far away as possible at 90 to the probable route of the target cable and clip the connector to the ground stake ensuring that a positive connection is achieved Position the locator approximately 2m (6 feet) from the ground stake and push the A-frame spikes into the ground with the green spike towards the ground stake Attach the locator to the A-frame by the retention hook. (If you are holding the locator separately, make sure that the locator is in line with the A-frame and is pointing towards the green spike.) The fault direction arrow should be pointing away from the ground stake. If it is not, make sure that the transmitter is connected correctly (red connector to the cable and black to the ground stake). 2023 Radiodetection Ltd 43 Take the dB reading and keep it for reference. If there is a single fault on the cable, it will be approximately the same dB value as the reference reading. NOTE. To establish how often to take readings on the cable or pipe, move away from the ground stake and take further readings until the arrow has difficulty in locking and the dB reading is low. Measure the distance that the locator is now away from the ground stake. This is the distance that you can safely use between taking readings on the cable or pipe to ensure that you do not miss the fault. 9.3 How to find a fault Starting from the transmitter, walk along the cable or pipe route pushing the A-Frame spikes into the ground with the green spike pointing away from the transmitter. Where there are no faults the dB reading will be low and the direction arrow may flicker forward and back. NOTE: Flickering arrows may also indicate that you may be too far away from the fault or ground stake (or both) for the locator to lock on. Figure 9.1: Cable sheath fault-finding If you are trying to locate high resistance faults or there is a long distance between faults, carry on with the survey and the locator will lock on when you get closer to the fault. Figure 9.2: Locating faults with the locator and A-frame Take readings at the survey intervals determined by the reference reading. To locate the cable or pipe while using the fault find signal during a Fault-Find survey, press the key once and the locator will switch to Peak locate mode. To use alternative antenna modes, press the key to step through available antenna modes. To get back to fault find mode step through all available antenna modes until the locator goes back to fault find mode. NOTE: While the A-Frame is connected to the locator, depth and current measurements will not be available. If depth or current measurements are required, remove the A-Frame lead from the locator. As a fault is approached the Fault-Find direction arrow will lock on to the fault signal, point forward and the dB readings will increase. When the fault is passed the arrow will point back towards the transmitter. Take readings at smaller survey intervals to determine the exact point of the fault. When the A-frame is directly over the fault the dB reading will drop as shown opposite. NOTE: The values given are for illustration purposes only and may not be the same as those obtained in other situations. To pinpoint the fault, turn the A-frame 90 to the cable or pipe and Fault-Find until the exact point is found. Where the arrow direction changes the center line of the A-frame is now directly over the fault. Mark the ground to show the position of the fault. Find the maximum dB reading in front of the fault by pushing the A-frame into the ground at small intervals. Note the dB reading. If the reading is approximately the same as the reference reading, you can assume that there is only one fault. If the reading is less than the reference reading, keep surveying the cable for other faults. NOTE: If the cable or pipe runs under a road, use the equipment as normal on the road surface as it can sometimes detect signals when working on blacktop, concrete, or paved surfaces. If necessary, try wetting the road surface. Pouring a very small amount of water around the bottom of the A-frame spikes before each Fault-Find will generally ensure a good ground connection. NOTE: If the cable or pipe runs under a paved surface, the fault can often be pinpointed by fault finding in the grass / soil adjacent to the paving. Reduce the distance between placing the A-frame spikes in the ground to allow for the increased distance to the actual fault position. 2023 Radiodetection Ltd 44 Current Direction (CD) 10.1 Understanding CD Current Direction recognition is a feature that helps to positively identify a line at points distant from the application of the signal. It is highly desirable, if not essential, for positive identification of long distance lines. These lines can be traced and positively identified through congested areas or when running parallel to other lines. The CD feature on the RD8200SG locators indicate the direction of the current flow on a line. Identity of the target line is established if the locator display indicates that the current is flowing forward and away from the point of application of the transmitter signal. A signal that has coupled onto adjacent lines finds a return path to the point of the original signal application. This is indicated by the locator arrow pointing back towards the transmitter. This is in contrast to the forward pointing arrow indicating the target line. The CD transmitter signal should be directly coupled to the target line with a remote ground connection. Most CD signals are low frequency, making them unsuitable for connection with a normal clamp or induction. These can however be applied with a transmitter CD clamp. Using Current Direction (CD) to aid line identification locators, and Tx-10 and Tx-10B The RD8200SG transmitters feature several CD frequencies to help you determine the direction of current through a target line. NOTE: The transmitter and locator must both have the same CD frequency or frequencies installed to enable the feature to be used. If you have more than one CD frequency installed ensure that the transmitter and locator are both set to the same CD frequency. CD frequencies on both the locator and transmitter will be denoted by the icon on the display. Figure 10.1: Current Direction To select the CD frequency, proceed as follows:

Transmitter 1 Switch the transmitter off 2 Connect the transmitter to target cable or pipe, either by Direct Connection or by using a CD clamp 3 Switch the transmitter on 4 Press the key until the CD frequency is displayed CD is a combination of two frequencies, a CD frequency and a locate frequency. Locator 1 Press the key until the CD frequency is displayed, indicated by the icon. 4 kHz CD RD8200SG models feature Current Direction using a 4 kHz frequency. This frequency is designed to enable you to use CD to identify a target line on higher impedance cables such as telephone cables and CATV. 2023 Radiodetection Ltd 45 10.2 CD reset About CD reset When you trace a signal on very long target lines, the transmitter signal gradually bleeds into the ground by capacitance. This means the remaining signal gradually changes. A CD Reset can be used to re-establish correct CD operation. the phase angle of To perform a CD reset:

While using any CD frequency, 1 Press and hold the key Alternatively 1 Press the key to enter the menu 2 Scroll to the CDR menu using the or keys To perform a CD reset, press and hold the key 3 Press the key to enter the CDR menu This is referred to as phase-shift and can occur whenever an alternating current signal is flowing in a system of conductors that have a significant capacitance or inductance. The relative phase angle between the two frequencies will alter, but only over extended distances. 4 Select YES 5 Press the menu key to reset CD and exit to the main 10.3 CD clamps & stethoscopes On both the CD / CM clamp and the CD stethoscope there is an arrow that indicates which way the clamp or stethoscope is facing in relation to the transmitter. If the arrow is pointing away from the transmitter when the CD reset is performed the locator display shows 000 and the bar graph reads 100%. If the arrow is pointing towards the transmitter, the locator display shows 111 and there is no bar graph reading. When using either of these accessories it is important to reset the CD at a known point, near the transmitter, before making any identification measurements Refer to Section 12 for more information on clamps and stethoscopes. Figure 10.2: CD reset Figure 9.2 illustrates a buried line with significant capacitance to ground. It illustrates the gradual phase-

shift that occurs along the line. The diagram shows a reference point on each waveform. At first, the reference point occurs right on the Peak of a positive half cycle (A). It gradually moves towards the zero crossing point (D) and ends up on the Peak of a negative half cycle (F). The direction has shifted from forwards to backwards. At the intermediate point (D) flow cannot be determined. At this point the CD arrows on the RD8200SG locator will flash on and off. In the example shown in the illustration, by returning to (C) which is the last point at which a CD reading was achieved, and performing a CD reset, the response at (C) will be equivalent to that of (A). the current In most cases the phase angle shift does not occur until many kilometers from the transmitter and in some cases a CD reset may only be required every 20 kilometers (15 miles). Performing a CD reset You should perform a CD reset every time you select a CD frequency. CD reset can only be performed when in CD mode. 2023 Radiodetection Ltd 46 Survey measurements RD8200SG locator models are capable of recording up to 1000 survey measurement records to internal memory. When a measurement is taken and saved, the RD8200SG locator will store the most relevant measurements taken and information, such as:

13.3 Locator clamps A cable or pipe is accessible at an inspection hole or manhole. NOTE: The standard clamp cannot be used with CD. A special CM / CD clamp is available to clamp the lower frequency CD signals. Connecting a clamp 1 Put the clamp connector into the accessory socket on the front of the RD8200SG locator. 2 Place the clamp around the pipe or cable and switch the locator on. 3 Set the frequency to the same as that on the transmitter. 4 Put the clamp around each cable in turn and note the the strength of bar graph response. Compare response from each cable. The cable with a substantially stronger response than the others will be the cable to which the transmitter signal has been applied. Figure 13.1: Connecting clamps To ensure that the target cable has been correctly identified, reverse the positions of the transmitter and locator and check that the strongest response is still received from the target cable by the locator in its new position. A locator clamp is used to positively locate and identify a cable when several cables are running close together. Locator clamp range A target cable can be identified in a chamber, on a tray or other access point by fitting a clamp to the locator and examining each cable in turn. Signal strength response shown on the locator display should be noted for each cable. Standard clamps The clamp plugs into the locator accessory socket and is used for cable identification at points where the cable can be accessed. The standard clamps are suitable for cables up to 130mm (5) diameter. When to use clamps Clamps can be used where:

2023 Radiodetection Ltd 52 conductors WARNING! Before applying or removing the clamp around a power cable, ensure that the clamp is connected to the transmitter at all times. The clamp may buzz or vibrate if it is placed around a power cable that has significant net current flow. This is normal and does not harm the equipment. Connecting the clamp Figure 13.4 Transmitter output socket Figure 13.2: Standard Clamp Small clamp The small clamp performs the same function as the standard clamp but is useful in cramped situations where there is insufficient access for the standard clamp. The small clamp is suitable for cables up to 50mm (2) diameter. Current Direction (CD) and Current Measurement (CM) clamp The CD / CM clamp plugs into the accessory socket of the locator and enables CD and current measurements to be made on individual cables. Figure 13.3: CD / CM Clamp This accessory is used to identify a particular cable that is bunched with several other cables or in close proximity to other cables. The combination of direction current and current magnitude is extremely useful for identification purposes. 13.4 Transmitter clamps The transmitter clamp fits around a pipe or cable and safely applies a signal to a live insulated cable without interrupting or disconnecting the supply. The clamp applies a very discriminating signal to a target line with reduced coupling to other lines. A clamp can sometimes be a more effective method of applying the signal than Direct Connection. The target line will carry the strongest signal. The other lines will carry the weaker return signal. If the system comprises only two conductors, they may carry equal signals. WARNING! Do not clamp around uninsulated live 7 Plug the clamp into the transmitter output socket. Figures 13.5. 13.6.: Connecting transmitter clamps 2023 Radiodetection Ltd 53 8 Put the clamp around the pipe or cable and ensure that the jaws are closed. Switch the transmitter on. The display will show the Clamp connected icon WARNING!. The transmitter must only be connected to live services using the appropriate accessory such as a plug connector or live cable connector. Figure 13.7 Clamp connected icon The line should be grounded (earthed) on each side of the clamp for the signal to transfer to the line. Ground the line if necessary. An insulated cable may be traced even if it has no actual ground connection, providing a reasonable length is buried either side of the clamp to provide capacitive coupling to ground (earth). 13.5 Transmitter external power supply The external Mains or vehicle power supplies provides an alternative and convenient method of powering the transmitter. WARNING!. The mains power supply rating are: 100-

240VAC, 1.3A. Always use an adequately rated detachable mains lead. NOTE: It is not necessary to make a ground connection from the transmitter when using the clamp. WARNING!. The mains power supply is not IP rated and should not be used in wet locations Transmitter clamp range Although transmitter and locator clamps look the same, they have different internal windings. To prevent the wrong clamp being connected, transmitters and locator clamps have plugs of a different orientation. Standard signal clamps The standard clamps apply the transmitter signal very selectively and effectively to a target cable up to 130mm

(5) in diameter using frequencies from 8kHz to 200kHz The standard and small clamps have a double spring action for positive toroidal contact. Small signal clamp The small signal clamp is useful for applying signals from 8kHz to 200kHz to a target cable in a pedestal or other place with limited space. The clamp is suitable for cables up to 50mm diameter. Current Direction (CD) clamp Figure 13.9: Transmitter DC Input To use the mains or vehicle power supply units connect them to the DC input socket in the transmitter before connecting them to the mains or vehicle supply socket.

optic micro ducting or other small non-conductive pipes, to the 33kHz Super Sonde, which with a depth range of 50 feet / 15m targets deep sewer pipes. Consult the precision locate accessory range brochure or web page on www.radiodetection.com for a full list of all available sondes and their technical specifications. The sonde radiates a Peak field from the center of its axis with a ghost signal at each end of the Peak. Move the locator a little way behind and then in front of the axis of the sonde to detect the ghost signals. Finding the two ghost signals positively confirms the locate. Reduce the locator sensitivity to lose the ghost signals but still indicate a clear Peak response directly over the sonde. Locator sensitivity is now set for tracing the duct or drain unless the distance between sonde and locator changes. Propel the sonde three paces along the drain or duct and stop. Place the locator over the supposed position of the sonde. Do not adjust the sensitivity level. Check that the sonde has sufficient range for the application and is dimensionally small enough and sufficiently robust for the application. Ensure that the frequency of the sonde corresponds with the locator frequency; the locator will not locate the sonde unless the frequencies are the same. Sondes are marked with their transmitting the means of propelling the sonde is available together with the correct fittings and couplings. frequency. Ensure that Preparation Insert a new battery into the sonde. A new battery or a freshly recharged battery should be used at the beginning of each day and preferably at the start of each new job. Before inserting the sonde, check that the sonde and locator are at the same frequency and working correctly. To do this, place the sonde on the ground at a distance from the locator that is equal to the rated depth of the sonde. Point the locator at the sonde with the antenna in line with the sonde (the opposite of using the locator to locate a line) and check that the bargraph reading exceeds 50% at maximum sensitivity. Propelling a sonde Sondes have a thread at one end for connecting to drain rods, or to other devices for inserting and propelling the sonde along a drain or duct. Sondes may be floated along drains at the end of a tether and floats are available for fitting to the sewer sonde and super sonde. Sondes can be strapped to high-pressure water jets or similar devices used for cleaning, maintaining and inspecting drains. Sondes used in underground drilling and boring operations are normally housed in the boring or drill head behind the boring or drill bit. Locating and tracing a sonde Insert the sonde in the drain or duct access and locate it while it is still just in view at the drain or duct entrance. Hold the locator vertical directly over the sonde with the antenna in line with the sonde. Adjust the locator sensitivity so the bar graph reads between 60% and 80%. Figure 12.10 Sonde deployment To locate a sonde:

1 Move the locator backwards and forwards and stop when the bar graph indicates a Peak. You can use the LCD compass to orient the blade of the locator with the direction of the sonde. 2 Rotate the locator as if the blade is a pivot. Stop when the bar graph indicates a Peak. Figure 13.11 Locating a sonde 3 Move the locator from side to side until the bar graph indicates a Peak. 4 Repeat 1, 2 and 3 with the antenna vertical and resting on or just above the ground. The locator should then be directly above the sonde with the antenna in line with it. Mark the position of the sonde and its direction. 2023 Radiodetection Ltd 55 5 Propel the sonde a further 1 or 2 meters, pinpoint, and mark the position. Repeat this pinpoint procedure at similar intervals along the line of the drain or duct until the survey is completed. The FlexiTrace can be used in two modes: Sonde mode or Line mode. In sonde mode only the tip of the FlexiTrace is energized whilst in line mode its whole length is energized. Checking sonde depth The RD8200SG locator will automatically display the depth of a located sonde providing the locator is correctly oriented and positioned above the sonde. Using the LCD compass as a guide, rotate the locator until the compass indicates the sonde is in East / West position. To use as a sonde, connect both transmitter leads to the FlexiTrace stud terminals. As the FlexiTrace terminals are not color coded it does not matter to which terminals the leads are connected. To use the FlexiTrace in line mode, connect the red transmitter lead to one of the FlexiTrace terminals and connect the black transmitter lead to a suitable ground connection. Figure 13.12: Calculating sonde depth Calculation method Pinpoint the sonde. Move the locator in front of the sonde and still with the antenna in line with it, increase sensitivity to find the Peak of the ghost signal. Move the locator to behind the sonde ensuring that the locator blade is always in line with the sonde. Find the null positions A and B (See Figure 8.10). Measure the distance between them and multiply by 0.7 to give an approximate depth measurement. Flexitrace The Flexitrace is a traceable plastic covered fiberglass rod incorporating wire conductors and is used for locating small diameter, non-metallic pipes to a depth of 3 meters. The Flexitrace can be inserted into a pipe or duct as small as 9 mm / 3/8 internal diameter, and with a minimum bend radius of 250mm. Batteries are not required, as the FlexiTrace is powered by any Radiodetection transmitter. The FlexiTrace has a maximum power rating of 1W. When using the FlexiTrace with a Radiodetection Tx-5 or Tx-10 transmitter the output limit must be set to 1W in the MAX P menu and the output voltage limit set to LOW in the MAX V menu. WARNING! Failure to follow the Tx-5 or Tx-10 instructions above may result in the tip of the FlexiTrace becoming too hot to touch, resulting in risk of personal injury and damage to the equipment. Figure 13.13: FlexiTrace 13.7 Stethoscopes When to use a stethoscope At times, it may not be possible to put a clamp around a cable because of congestion or because of inaccessibility. A stethoscope antenna should be used in place of a clamp to identify the target cable(s). How to use a stethoscope Plug the stethoscope into the locator accessory socket. Press the concave head against each cable in turn to detect a maximum signal. Stethoscope range Large stethoscope antenna The large stethoscope antenna, which plugs into the locator accessory socket, is used for cable identification in situations where the cable is exposed. It is particularly useful for identifying heavy cables lying in a tray where it is not possible to fit a clamp. The concave detector head on the end of the insulated, flexible gooseneck is placed firmly against the cable to be identified. If there are a number of cables, the stethoscope antenna will give the strongest response from the cable to which the transmitter signal has been applied. Small stethoscope antenna The small stethoscope antenna has a 25mm (2) concave head at the end of a 2m (6 ft) lead. The small stethoscope can be screwed into an extension rod or used at the end of several extension rods joined together for identifying inaccessible small cables. 2023 Radiodetection Ltd 56 Miniature hi-gain stethoscope Tips for using a submersible antenna:

The user in the boat should be a specialist or have considerable experience using a locator so that they can give concise instructions to the diver. It is prudent for the pair to practice working together on dry land before attempting to locate underwater. Using the antenna, the diver should locate and trace a known line blindfolded receiving directions from the user with the locator out of sight of the line and the diver. Because of rapid signal loss and a combination of large surface area and very conductive soil there may be problems applying a suitable signal for tracing a large diameter pipe. It may be necessary to use a high power, low frequency tracing signal. It is necessary to define a method of recording target line position and depth before starting work in the boat or on the seabed. Figure 13.14: Using a submersible antenna WARNING! Only properly licensed and experienced divers should attempt to use the submersible antenna. the small The miniature stethoscope stethoscope but has no handle or facility for extension rods. is similar to The miniature stethoscope can also be used as a miniature antenna for locations where the bulk of the locator makes it inconvenient for use, such as locating pipes or cables in walls. CD stethoscope In restricted areas, the CD stethoscope can be used to obtain current direction but not current measurement. 13.8 Submersible antenna When to use a submersible antenna Tracing buried pipes and cables across waterways and estuaries are frequent and critical locating applications. Less frequent but equally important is tracing and locating lines between the mainland and offshore islands. When locating pipes and cables the locator sensing antennas should be as close as possible to the target line so it is not practical to locate lines buried under a river or seabed from the surface. In most cases, it is necessary to measure the depth of cover to ensure the line is protected from dragging anchors or other underwater hazards. The submersible, double depth antenna is suitable for use under water for tracing pipes or cables. There is a weight at the bottom of the antenna for stability and the unit has been pressure tested to IP68 to a depth of 100m (300ft). The antenna is supplied with 10m of submersible marine umbilical cable as standard, but lengths of up to 100m can be supplied. The extra length enables the antenna to be carried by a diver on a riverbed or seabed while the locator is used in a surface vessel. It is crucial to have effective communication between the operator with the locator and the diver with the antenna. Alternatively, the antenna can be fastened to the end of a non-metallic boom from a barge and lowered to the riverbed or seabed. How to use a submersible antenna Apply the transmitter signal to the target line at an access point on the shore. The submersible antenna line for tracing the line underwater is plugged into the accessory socket of the locator. The locator is used onboard a boat, which should by positioned directly over the line. The transmitting signal should be applied by Direct Connection with the strongest possible signal and at the frequency that the submersible antenna is calibrated to. Make a ground connection about 50m (160ft) from the transmitter. Test the quality of signal on the line before locating on the water. NOTE: The submersible antenna is calibrated to work at one frequency. 2023 Radiodetection Ltd 57 Appendices 14.1 Care and maintenance The RD8200SG locator and transmitter are robust, durable and weatherproof.
