PREFACE PIPEHAWK PLCS new PipeHawk has been developed using State of the Art technology. This technology offers a means of accurately pinpointing underground piping, whether plastic or metal, providing the operator with an immediate display of its location. The PipeHawk has been built to very high standards, but will require some care and attention. This manual has been designed with the same care as your PipeHawk and will provide information on the Operating and Maintenance procedures necessary for the machine to function to the designed performance and reliability. Read this manual carefully before operating the machine. It should be kept with or near the machine for easy reference. The PipeHawk single channel ground probing radar system. PipeHawk radiates a low level radio signal into the ground. Public concern and awareness has been raised about the safety of such systems particularly with regard to cellular telephones. There is no danger to personnel in this regard, during normal operation of PipeHawk. The average power radiated is less than a cellular telephone, it originates in the white antenna some distance away from the operator and is directed downwards into the ground where it is dissipated. It should be noted that as with all radio systems there is the remote possibility that they may cause mutual interference. GPR is no different in this respect. In the UK, the trade association, EuroGPR, has agreed a Code of Practice with the Radiocommunications Agency to manage these unlikely events. The code draws operators attention to the increased sensitivity that may surround some radio installations such as airports, prisons, or defence establishments. Copies of the Code of Practice may be obtained from the EuroGPR Secretariat at The Association Bureau, PO Box 1381, Rugby, Warwickshire, CV21 2ZF, or from PIPEHAWK PLC. WARNING All Operators of the PipeHawk should make themselves fully aware of the information presented in this manual. Service of this machine is to be carried out only by fully trained and authorised personnel. PipeHawk plc 2003 Page 1 PipeHawk Operators Manual 100049000-C 1.0 INTRODUCTION PipeHawk is a ground penetrating radar system or ground probing radar system (GPR) designed to locate and map the position of buried pipes and cables. Whilst PipeHawk may be used to locate a range of different types of anomalies its on board specialist software is designed only for the detection of linear features, which may normally be interpreted as buried pipes and cables. The system is designed for one person operation in the field. PipeHawk surveys the area of interest by traversing a grid of linear measurement lines termed scans in order to build up information concerning the underground environment. The depth surveyed varies according to the subsurface ground conditions, and is normally characterised by the depth of penetration of the radar signal. The average penetration will be greater in sandier regions than in clay regions, but will typically be in the range 2.0m to 2.5m. In exceptionally good or exceptionally bad conditions the depth may exceed 3m or be restricted to 1.2m to 1.5m. The radar is used by being pushed over a linear path to complete a radar scan. When the scan is completed the operator is presented with a virtual image representing a cross section through the ground scanned. The horizontal axis of the image represents the 3m path just surveyed and the vertical axis the depth into the ground. Radar targets, corresponding to objects in the ground are shown as bright areas in a format specified by the processing applied. PipeHawk is a sensitive radar and has the capability to detect the presence of pipes and cables, and a range of other objects. The operating procedures and processing software has therefore been designed to build up a comprehensive view of the underground environment, to allow pipes and cables to be distinguished from other objects as linear features. In a sophisticated system like PipeHawk there are many features that contribute to the operation and use. This document necessarily must present a wide variety of information and is intended to act as a simple reference for operators, who should have been on an approved PIPEHAWK PLC PipeHawk training course. This document begins with a brief description of the PipeHawk radar and a basic technical specification. PipeHawk plc 2003 Page 2 PipeHawk Operators Manual 100049000-C 2.0 TECHNICAL SPECIFICATION 2.1 Radar System The PipeHawk operates by introducing a fast risetime electromagnetic pulse into the ground. The pulse is scattered by changes in the electrical properties of the ground. The presence of metal generates a major change in electrical properties but the system is sensitive to other changes such as the presence of plastic, water, or air. The scattering produced by changes in ground conditions returns a small fraction of the energy back to the radar. Figure 2.1 shows a general schematic of the radar part of the system, with a pulse generator acting as a transmitter, feeding a signal to the antenna to be introduced into the ground. The signal returned is then received by the antenna, where it is passed to the digital signal processing hardware for manipulation into a suitable format for display. The transmitter, antenna elements, and sampling receiver are all found in the white plastic moulding typically described as the antenna. The yellow case houses the Main Electronics, the display, the battery, and the wheel sensor. The main power supplies for the system and the signal processing are contained in the Main Electronics. There are two major computer boards and a hard disc.

PipeHawk plc 2003 Page 6 PipeHawk Operators Manual 100049000-C 3.0 MAINTENANCE AND CARE OF PIPEHAWK 3.1 Care of PipeHawk The main requirements for the care of PipeHawk are that: -

i. ii. iii. iv. v. vi. The system should be kept clean. The underside air vents should be free of obstruction or debris. The antenna should be fitted with a wear membrane that is complete and free from holes or other excess wear. The tyres should be inflated to the correct pressure of 0.71 kg/cm2. A suitably charged battery should be employed. There is adequate space on the hard disc to store data from the intended site investigation. All other work should be referred to PIPEHAWK PLC or an authorised dealer. The system must be serviced periodically, dependent upon use, with the mechanical parts such as bearings checked for wear and the electronics calibrated. This shall be carried out every twelve months of normal use or six months of heavy use. Check the underside air vents are clear of debris. CAUTION Caution shall be exercised when cleaning the system. The minimum amount of water shall be used and pressure must be avoided. It shall be noted that although the main electronics are sealed, the main case contains some sponge like black anechoic material. If this is wet, the performance of the system will be degraded. Household detergents and water shall be used for cleaning the system. Other cleaning agents may damage the powder or plastic finishes and should not be used. 3.2 The Antenna Wear Membrane The PipeHawk antenna rests upon the ground. When the system is pushed along to complete a radar scan, the antenna is potentially worn by the surface of the ground. A sacrificial plastic wear membrane fits over the antenna to prevent such damage to the antenna itself. Under NO circumstances should the machine be operated without a wear membrane in place. Check membrane daily for wear. If any part of the membrane is worn through it must be replaced immediately. PipeHawk plc 2003 Page 7 PipeHawk Operators Manual 100049000-C 3.3 Pneumatic Tyres It is important that wherever pneumatic tyres are fitted they are inflated to the correct pressure. For PipeHawk it is particularly important that the pressure is correct because a wheel sensor is fitted which is employed to trigger the radar and measure horizontal distance. Incorrect inflation changes the wheel diameter, and leads to inaccurate horizontal distance measurements. Excessive mud and debris should not be allowed to build up on the wheels because this produces similar errors. Do not over inflate check pressure daily. The tyre pressure should be 0.71 kg/cm2. 3.4 Battery and Battery Charging PipeHawk uses a 24V, 9.5 AH sealed lead acid battery, housed in a black plastic moulding. The battery life is approximately four hours, dependent upon the use made of the system. When fully charged, the battery voltage exceeds 24V. As the charge is used the voltage drops, and the battery must be re-charged when the battery voltage drops below 20V. In the main measurement mode, a low battery warning light will appear when the voltage drops below this critical voltage. If ignored the PipeHawk will shut down automatically. The software structure is such that in other menus this facility is disabled to allow functions such as uninterrupted file transfer to be carried out. If the operator is not using the measurement menu for long periods, then the battery voltage must be regularly checked via the Tools and Status Menus. It should be noted that battery performance degrades with time, with excessive temperatures and with the number of battery charging/discharging cycles. As a guide, the battery manufacturers indicate that if the battery is used regularly and not subjected to any extreme conditions its life should approach 500 cycles. This can not be guaranteed by PIPEHAWK PLC. A battery charger is provided with the system. This is the only charger that should be used to re-charge the PipeHawk batteries. Use of other chargers may have a significant adverse effect on the life of the batteries and will invalidate any guarantees. Care is required in connecting the battery charger to the battery. The connectors are shaped so that they can only be connected one way. The cover of the battery charger must not be removed. The charger must be connected to the mains network in accordance with wiring regulations, only after checking that the voltage rating of the charger is compatible with the local electricity supply. 3.5 Disc Management Prior to operation each day, the availability of space for data storage upon the hard disc should be checked. This is done on the Hard Disc Status menu, which includes an indication of the length of measurement that can be completed before action is required to remove data from the system. If action is required, the File Transfer Menu, detailed later, should be accessed. It is recommended that data is down loaded and archived on a regular basis. PipeHawk plc 2003 Page 8 PipeHawk Operators Manual 100049000-C 4.0 THE USER INTERFACE 4.1 Introduction The PipeHawk user interface is designed for simplicity of use, and is based around a backlit liquid crystal display (LCD) and seven user softkeys. Icons at the bottom of the display immediately above the switches indicate their current function. The icons generally do not include text and therefore may be considered to be international. The display is divided into five main areas (see figure 4.1), with the largest area available for data. There are two areas immediately adjacent to the data area that may be used to present subsidiary data to that in the main area, for example horizontal and vertical depth scales. Seven icons appear along the bottom of the display. The small remaining fifth area of the display is employed for warnings, typically low battery voltage. The seven softkeys are coloured yellow, apart from the first softkey from the left, which is coloured green. When this button is depressed with the PipeHawk switched off, the system is powered on. Various set up menus are then briefly displayed, before the Main Menu shown in figure 4.1 appears. All the operating functions of the system may be accessed beginning with this menu. Figure 4.1.............Main Menu PipeHawk plc 2003 Page 9 PipeHawk Operators Manual 100049000-C The subsidiary menus that are accessed from the Main Menu are: -

Changing Display and Scales Menu Modem Menu Status Menu Data Collection Menu Data Review Menu Data Transfer Menu Power Down Menu It should be noted that in all subsidiary menus, the right hand softkey, number 7, exits the menu back towards the Main Menu. The most important operational menus are the Data Collection Menu, the Data Review Menu, and the Data Transfer Menu. These will be dealt with in subsequent chapters but the other menus will now be presented. 4.2 Changing Display and Scales Menu The Changing Display and Scales Menu may be used to set the default settings on the display to monochrome (16 levels) or colour (256 colours). It also allows measurement scales to be changed between Metric and Imperial. Once set within this menu the scales menu selection will remain the default even when the machine is turned off and then rebooted. The display setting will revert to colour upon reboot.

This may be for uploading of new software to the PipeHawk or diagnostic work by PIPEHAWK PLC engineers. Modems are not supplied to PipeHawk customers as telephone regulatory approval varies around the world, and modems must be approved by local administrations. The recommended modem is : -

3COM US Robotics 56k Fax Modem (V90-x2) Please note other modems may not work. For information on where to purchase this modem visit www.3com.com. The procedure for a modem link up with PIPEHAWK PLC is as follows: -

1. Contact the PIPEHAWK PLC customer service department, and inform them of your direct dial telephone number. This is the telephone to which the modem will be attached. Advise of a time when connection can be made and the reason for a modem link up. 2. Attach the adapter cable to the rear of the PipeHawk using the circular connector. Attach the small serial D connector on the other end of the cable to the modem cable, and hence the modem cable to the modem. PipeHawk plc 2003 Page 11 PipeHawk Operators Manual 100049000-C 3. Connect the modem to the externally available telephone line detailed in 1), and also connect to a power supply. 4. Turn on both modem and PipeHawk. 5. In the Main Menu: -

Press Key 2 PipeHawk is now ready for an external connection to be initiated by PIPEHAWK PLC. 6. On a separate telephone line it may be helpful to advise PIPEHAWK PLCs customer service department that PipeHawk is ready for a modem connection. 7. Connection will now be made by PIPEHAWK PLCs customer service department to make any modifications required. Once complete, turn off the PipeHawk, and disassemble all peripherals. 8. PipeHawk should then be switched on again, to test the system. 4.4 The Status Menu Within PipeHawk the Status Menu enables the user to check on basic diagnostic functions such as battery voltage (nominally 24V), internal and external machine temperature and antenna type. Of the above, the PipeHawk is self regulating in terms of temperature. The most common use for this menu is to monitor battery life at the start of a working day and the type of antenna currently connected to your PipeHawk. 4.4.1 To Access the Status Menu from the Main Menu Press Key 3 This accesses the Status Menu. 4.4.2 To View the Status of the System Press Key 2 The status of the battery voltage together with other voltages and temperatures is now displayed. 4.4.3 To View the Status of the Hard Disc Press Key 6 The status of the hard disc is now shown as a bar graph, in terms of the percentage of the hard disc that is full of data. (The hard disc allows at least 2 GBytes of data to be stored). The display also indicates how many more 3m scans may be recorded before essential down load. PipeHawk plc 2003 Page 12 PipeHawk Operators Manual 100049000-C 4.4.4 To Exit the Status Menu and Return to the Main Menu Press Key 7 Exits the Status Menu and returns to the Main Menu. Note: When viewing the PipeHawk Status Screen, a number of other icons and their relative keys are displayed. Key 3. Key 4. Key 5. These keys are solely for the use of the PIPEHAWK PLC customer service department and should not be accessed by user unless instructed to do so by PIPEHAWK PLC. Pressing these keys can detrimentally affect the performance of your PipeHawk if done by anyone other than an PIPEHAWK PLC technician. If in doubt refer to PIPEHAWK PLC for advice. PipeHawk plc 2003 Page 13 PipeHawk Operators Manual 100049000-C 5.0 CONFIGURING AND USING PIPEHAWK FOR DATA COLLECTION (THE DATA COLLECTION MENU) 5.1 Introduction In order to obtain the optimum performance from PipeHawk it is necessary to set up and use the system in a prescribed manner. This then allows data to be collected in the field and to be suitably documented if returned to the office for processing or archiving. Radar data is collected by PipeHawk in terms of 3m scans, or linear movements of the system. Generally a data file consists of seven such parallel scans which are collected 0.5m apart and characterise a 3m x 3m area. Each scan in the data set is given an extension number, typically .001 to .007 recording the order in which the data is collected. The operator may choose to record between one and five continuous 3m scans, corresponding to a total length of 3m to 15m. The operator may choose to enter a name that will be associated with the data set. If multiple scans are specified then a numerical suffix is added to the title of the second and subsequent files. The operator may choose to carry out measurements by pushing the system forwards or pulling the system backwards. The operator may also set the number of data averages carried out. This process is termed stacking and may aid signal quality. The more stacking that is carried out the higher the signal quality that may result, but the slower the speed at which the operator must push the PipeHawk. The number of stackings available ranges from 1 to 128, each increase doubles the value, ie 1, 2, 4, 8, 16, 32 etc. The default value of 8 should be used in most circumstances. With 32 the speed must be low. Higher stacking numbers may be required for deeper pipes. All of the above parameters must be set to configure the PipeHawk to be ready to carry out radar measurements. The configuration steps will now be presented. 5.2 Configuring the PipeHawk for Scanning 5.2.1 To Access the Data Collection Menu from the Main Menu Press Key 4 Accesses the Data Collection Menu. The operator should then select the number of continuous 3m radar scans to be undertaken. The default value is 1, the maximum is 5. PipeHawk plc 2003 Page 14 PipeHawk Operators Manual 100049000-C Press Key 2 To increase the number of continuous scans. OR Press Key 3 To decrease the number of continuous scans. The operator should then select the stacking number. The default value is 8. Press Key 4 To increase the stacking number. OR Press Key 5 To decrease the stacking number. When the operator has made the selection for the number of continuous scans and the stacking number, the question displayed, New Site?, should be answered. The options are: -

Press Key 1 OR Press Key 6 For yes. This action displays the menu for entering a new site name. This actions allows an For no. incomplete measurement to be continued (for example if the battery had become exhausted before completion). 5.3 Entering a Data Set Name The seven softkeys are used to enter the Data Set Name. Two keys allow the operator to scroll through an extended alphabet in opposite directions to allow the next letter of the name to be selected. Other keys allow the selected letter to be added to the name, or the last letter entered deleted. A further facility is the ability to recall the last name used and to edit it. This saves time when a whole series of files are to be named, which differ by the final number being progressively indexed. PipeHawk plc 2003 Page 15 PipeHawk Operators Manual 100049000-C 5.3.1 Selecting a Character to Add to the Data Set Name Key 1 Key 2 Progresses through the extended alphabet from A to Z. Progresses through the extended alphabet from Z to A. 5.3.2 Delete the Last Character from the Data Set Name Key 3 Deletes the last character. 5.3.3 Include the Selected Character to the End of the Data Set Name Key 4 Includes the selected character. 5.3.4 Recall the Last Data Set Name Key 5 Recalls the last data set name. 5.3.5 Confirm the Created Data Set Name Key 6 Key 7 Confirms the created data set name and enters it into the memory of the PipeHawk. All scanning will now be collated under this name until a new name is entered. This key causes the Data Collection Menu to be displayed. Return to the Main Menu, causing the measurement to be aborted. 5.4 Data Collection Site Procedures If the operator wishes to take advantage of the mapping facilities available with the PipeHawk software, then it is necessary to observe simple site procedures to ensure that the maps generated are a representation of the area scanned. PipeHawk plc 2003 Page 16 PipeHawk Operators Manual 100049000-C The figure below shows the protocol to be observed. It shows a 3m x 3m area to be scanned and the position of the scans if the mapping software is to be employed. As the operator approaches the area to be scanned, the first scan should be at the left of the scan start line, with subsequent scans progressively spaced to the right. Scan Start Line Scan 1 Scan 7 3m x 3m square to be scanned Figure 5.4.............Site Protocol to be Observed if the PipeHawk Mapping Facilities are to be Employed 5.5 Data Collection Menu When either the new site data set name (5.3.5) is confirmed or the no new site key (key 6, 5.2.1) is pressed while configuring the PipeHawk, the Data Collection Menu is entered. The PipeHawk should then be placed with the antenna aligned with the scan start line, and facing the measurement direction. Data collection may then take place. 5.5.1 Setting the Scanning Direction Press Key 5 To select the scanning direction, which is displayed either as a right or left pointing arrow, in the Icon of Key 1, depending whether the scanning direction is forwards or backwards respectively. PipeHawk plc 2003 Page 17 PipeHawk Operators Manual 100049000-C 5.5.2 Initiating the Scanning Process Press Key 1 Forwards scanning. OR This initiates the scanning process, pushing or pulling PipeHawk as indicated by the direction of the arrow will trigger the radar to collect data. Backwards scanning. The operator should push the machine until the scan is complete. The scanning process will stop automatically upon reaching 3m, 6m, 9m, 12m, or 15m point determined in Section 5.2 Configuring the PipeHawk for Scanning. If the operator is unable to complete the scanning process, possible because the path is obstructed, the scan may be terminated before it is complete. 5.5.3 Terminating a Scan Press Key 3 This will stop the scanning process early. This may be used if an obstruction is reached and the machine can not be pushed or pulled further. When a scan has been stopped early the operator may either save the scan to memory or prevent it from being saved. 5.5.4 Save a Scan that has been stopped early?

Press Key 1 This will save the scan to memory. OR Press Key 7 This will prevent the scan from being saved to memory. In normal operation, at this point the operator has completed one scan. If the mapping facilities within PipeHawk are to be employed, then the operator must position the system at the start of the second or subsequent scan as defined in figure 5.4, in the previous section. The operator should then re-initiate the scanning process as defined above and complete the required series of scans. PipeHawk plc 2003 Page 18 PipeHawk Operators Manual 100049000-C 5.6 On-Site Data Review Whilst in the Data Collection Menu referred to in the previous section, the Pull Back Function is available. This facility is an aid to on-site mark out, and is only available immediately at the time of measurement. The on-site data review functions available are: -

5.6.1 The Scan Selection Function Press Key 2 OR Press Key 3 5.6.2 The Pull Back Function This allows the user to review other scans already collected within the data set. One key selects earlier scans and one key later scans than currently displayed. Press Key 4 The Pull Back Function when activated will put a vertical line or cursor, at the right hand side of the display, which is indicative of the centre of the antenna

(see figure 5.6). By physically moving PipeHawk along the scan line the cursor will move through the data display and enable the user to position the antenna directly over the centre of the target. Arrows are marked on the side of the antenna to indicate where the ground should be marked. Key 4 is again pressed to turn the pull back facility off. PipeHawk plc 2003 Page 19 PipeHawk Operators Manual 100049000-C Figure 5.6.............Pull Back Display 5.6.3 Data Processing Options Press Key 6 5.6.4 Return to Main Menu Press Key 7 This allows the user access to the processing controls and hence the ability to view single scan data in more than one processed format. The options available are the same as in the Data Review Menu (see Section 6.0). Return to Main Menu. PipeHawk plc 2003 Page 20 PipeHawk Operators Manual 100049000-C 6.0 DATA REVIEW 6.1 Introduction The Data Review Menu and functions allow the operator to process and review the data that is stored on the hard disc. These features may be used at any time after the data is collected. When used for on-site mark out, this is immediately after the data collection and provides access to the mapping functions, and a more complete view of the area surveyed, while still on-site. The data review process involves the selection of the data from the hard disc and the application of a range of processing options and procedures to the data. 6.2 Data Selection The Data Selection Menu is accessed from the Main Menu by: -

Press Key 5 The Data Selection Menu is then displayed. The Data Selection Menu displays a list of all the data files or data sets recorded on the hard disc. (If the system has not been down loaded for a long time this list may be long and slow down operations). The data displayed for each file includes the name generated in Section 5.3 and the time and date when it was created. This corresponds to the time and date the first scan was carried out. Data is selected by scrolling a cursor, the > symbol down the left hand side of the list and then selecting a chosen data set or sets, when the *, indicates the set which is selected. When the selection is confirmed the first scan of the chosen data set is displayed in the Data Processing Menu. 6.2.1 Data Selection Press Key 1 OR Press Key 2 This scrolls the user up and down through the sequential list of data sets collected and stored on the machine. Move the > symbol to indicate a chosen data set. PipeHawk plc 2003 Page 21 PipeHawk Operators Manual 100049000-C 6.2.2 Select Data Press Key 3 OR Press Key 4 Highlights the chosen data set with an asterisk *. Pressing again deselects the data set. Highlights all data sets in memory for selection and review. (To take advantage of this feature generally requires effective management of the hard disc (see Section 7.0), so that typically when this feature is selected all the data collected in a days measurement is processed). 6.2.3 Data Processing Options Press Key 6 6.2.4 Return to Main Menu Press Key 7 This allows the user access to the processing controls and hence the ability to view single scan data in more than one processed format. The options available are the same as in the data review menu (see Section 6.0). Return to Main Menu. 6.2.5 Confirmation of Data Selection Press Key 5 Confirms the selection of data set(s). The first scan of the first data set is displayed in the Data Processing Menu. 6.3 Data Processing Following the data selection process the first scan of the selected data set is displayed, and the operator is presented with a series of review options. These include the ability to: -

i. ii. iii. iv. v. Scroll both ways through the scans of the data set. Overlay a measurement grid to the data. Produce a map or plan images from the data set. Select a number of different processing options. Print scan or map images of the data. PipeHawk plc 2003 Page 22 PipeHawk Operators Manual 100049000-C Each of these options will now be presented. 6.3.1 Scrolling Through Scans Press Key 1 OR Press Key 2 6.3.2 Scale Grid Overlay Press Key 4 6.3.3 Processing Options Press Key 6 6.3.4 Mapping Press Key 5 6.3.5 Printing Press Key 1 6.3.6 Return to Main Menu Press Key 7 This allows the operator to scroll up and down through the scans of the data set. Depressing this key either switches on or off the scale grid overlay depending upon its initial state. This selects the Processing Options Menu that allows the data to be processed in different ways. This selects the Mapping Menu, which processes the data to produce map or plan images of the area surveyed in the selected data set. Prints the radar scan currently displayed. (A further print option is present in the Mapping Menu). Return to Main Menu. PipeHawk plc 2003 Page 23 PipeHawk Operators Manual 100049000-C 6.4 Processing Options Menu The Processing Options Menu allows data to be analysed in different ways. The two major options are identified as ID 2, which is the default at switch on, and ID 5, which provides the most effective processing for pipe location and mapping. These two options should primarily be used. ID 2 may be recommended when PipeHawk is employed for data collection tasks where there is minimum review on-site. ID 2 incurs no processing delay but provides a representation of signals from pipes that can be recognised with experience. ID 5 carries out extensive processing and presents the radar data to the operator in the simplest format, but a processing delay occurs. Two representations of the same data processed by ID 2 and ID 5 are shown in figures 6.4.1 and 6.4.2. ID 2 shows the response from a pipe as an extended hyperbola, ID 5 presents a much simpler representation of the same pipe. Figure 6.4.1..........ID 2 Processed Data PipeHawk plc 2003 Page 24 PipeHawk Operators Manual 100049000-C Figure 6.4.2..........ID 5 Full Processing The images displayed are virtual cross-sections through the ground indicating the presence of a sub-surface anomaly. In ID 5 the target position can be determined approximately in both horizontal position and depth. PipeHawk is fitted with extensive software that enables data to be processed in a number of different ways. The different processing routines allow the operator to select from either simple procedures that are almost instantaneous, through to extensive procedures that incur a short delay before the data is displayed. The different processes have different identification numbers (IDs) which are detailed below: -

Process ID Types ID 0 ID 1 ID 2 ID 4 ID 5 Raw Data Profiled Raw Data Pre-processed Data Processing Full Processing PipeHawk plc 2003 Page 25 PipeHawk Operators Manual 100049000-C ID 8 ID 9 Raw Data Waveforms (Service Use Only) Processed Raw Data Waveforms (Service Use Only) Details of the user options are presented below: -

6.4.1 ID 0 Raw Data This is a grey scale representation of the raw data as recorded by PipeHawk, without any significant processing. Generally, the attenuation of the ground means that little information is displayed from deep targets. 6.4.2 ID 1 Profiled Raw Data This is a grey scale representation of the raw data after it has been profiled to compensate for the effects of loss in the ground. Profiled raw data requires experienced user interpretation but does allow the data from PipeHawk to be interrogated for non pipe like sub surface features. 6.4.3 ID 2 Pre-processed Data This is a grey scale representation of data that has been processed to enhance the presence of pipe like features whilst suppressing layer and background information. This is the default setting upon power up. Using this process the results are displayed to the operator almost instantaneously, however experienced interpretation is required. 6.4.4 ID 4 Processing This is a cut down version of the full processing algorithm. It is designed to provide the user with a fast interpretation of the sub-surface situation. It should be noted that this processing option will not provide the same degree of accuracy as the full processing option ID 5. 6.4.5 ID 5 Full Processing Full processing displays the response from each target as a compact response indicating the position of a target. The other processing options available is to change the profile correction applied to the data to accommodate different soil characteristics. Like ID 0, ID 1, and ID 4, this feature should only be applied by experienced radar operators. The default profile corresponds to average soil conditions, but the options are: -

Very low loss Low loss Average High loss Very high loss PipeHawk plc 2003 Page 26 PipeHawk Operators Manual 100049000-C If an incorrect profile is being used information will only be displayed from part of the depth range of the system. Either there will be an emphasis on displaying shallow targets or deep targets. If only shallow targets are shown the profile may be changed to correspond to a higher loss situation. Similarly if only deep targets are shown it may be desirable to use a lower loss profile. 6.4.6 To Access the Processing Options Menu Press Key 6 Accesses Data Processing Options Menu. 6.4.7 Changing the Processing ID Number Press Key 1 OR Press Key 2 6.4.8 Changing the Profile Press Key 4 This cycles through the processing options. Pressing this button cycles the profile sequentially through the options from low to high loss. The default is average. 6.4.9 Confirm the Processing Options Press Key 3 Press Key 7 6.5 Mapping Menu Any changes in the processing options ID number or profile must be confirmed by pressing this key before they are implemented. This returns the user to the Data Processing Menu, where if it is pressed a second time the user is returned to the Main Menu. When the Mapping Menu is accessed from the Data Processing Menu, which should be with ID 5 selected, the system sequentially processes each of the radar scans in the data set starting with the first scan. During the processing the display shows the scan processed, and the information below it indicates the scan number of the data that is currently being processed. PipeHawk plc 2003 Page 27 PipeHawk Operators Manual 100049000-C When all the radar scans corresponding to cross-sections in the ground have been processed, the scans are placed side by side, in the manner specified by the site procedures detailed in section 5.4, to form simple maps. The top left of the map corresponds to the starting point of scan 1 in the area surveyed, with the top right corresponding to the end point of scan 1. There are a number of map options. The simplest option is the SUM map and corresponds to viewing all the radar returns summed together regardless of depth. If only one pipe or cable is present this produces an effective map showing its plan position, as a continuous line on the screen. In complicated environments, where there are many pipes this simple map may be confused by several pipes at different depths. For these situations the map may be divided into seven equal depth slices, which together represent the full depth recorded. In the display upon PipeHawk only one map may be shown at any one time, but if the print option is employed, all eight maps are printed out upon one sheet of paper as shown in figure 6.5. This shows the maps corresponding to layers 0 to 6 and the sum layer. PipeHawk plc 2003 Page 28 PipeHawk Operators Manual 100049000-C Figure 6.4.............An Example of the Printed Output from the Mapping Option PipeHawk plc 2003 Page 29 PipeHawk Operators Manual 100049000-C The Mapping Menu key press functions will now be defined. 6.5.1 Scroll through Map Layers Press Key 1 OR Press Key 2 6.5.2 Map Printing These keys allow the user to scroll up and down through the map layers to identify the position of linear features. At any time whilst within this Data Processing Menu a user may print out the data displayed on screen. This is usually sent to the Cannon Bubble Jet Printer provided with the PipeHawk. Assuming the adapter cable and printer cable are attached to the PipeHawk, printing can be carried out as below (the Cannon Bubble Jet is the default printer). Press Key 4 Prints the map output (figure 6.5). 6.5.3 Viewing Other Selected Data Sets Once printing has been carried out the user can view other highlighted data sets by the method outlined below. Press Key 5 OR Press Key 6 This shows other maps created from corresponding data sets. Again these can be printed as required. PipeHawk plc 2003 Page 30 PipeHawk Operators Manual 100049000-C 7.0 DATA MANAGEMENT 7.1 Introduction PipeHawk is a data measurement and recording system, and for effective operations it is essential that the data captured is properly managed. In order to achieve this three data management procedures are available within the system, they are: -

i. ii. iii. The ability to down load or transfer data, from PipeHawk to a PC. This is normally required when the user has purchased the Office Processing Suite, or for data archiving. The ability to transfer data from an external client PC to PipeHawk. This may be required if the PipeHawk system is the only processing system available for radar data, and it is required to process archived data. The ability to delete redundant data from PipeHawk. Normally this procedure would be carried out after the data has been transferred to an external PC, and the user has verified the integrity of the transferred data. Best practice data management procedures, indicate that the PipeHawk data should be routinely removed from the system, and office based back-up copies made. Although PipeHawk has a large hard disc, disc access times may increase if it contains many files and this may slow down operations. The three data management functions are all accessed from the Data Transfer Menu and will now be presented. They all require that the PipeHawk system is connected to a separate PC. PipeHawk must be turned off before connecting the adapter cable to the military style connector on the back plate of the machine. From here, the supplied down loading cable

(parallel) should be attached to the adapter cable and hence to the printer (parallel) port of the Client PC to be used for down loading. In order to facilitate data transfer to or from a Client PC, the operator must select the data to be moved, the directory to be used on the Client PC either as a receptacle or source for data, and the data transfer direction. If data is to be transferred to the Client PC, a data directory should be created within that machine to store the data. This can be done either by using Windows Explorer or via a few simple DOS commands. When the directory is available double click on the Transfer icon on the Client PC (see transfer software installation, in the Transfer Software Manual if not already installed on PC). The Client PC is then ready to accept data and PipeHawk should be turned on. PipeHawk plc 2003 Page 31 PipeHawk Operators Manual 100049000-C 7.2 Data Transfer from PipeHawk to the Client PC 7.2.1 Access the Data Transfer Menu from the Main Menu Press Key 6 The Data Transfer Menu is accessed allowing the Client PC and PipeHawk to recognise each other and to communicate. The Data Transfer Menu is then displayed. Near the top of the display is shown the options: -

GO TO PH DIRECTORY GO TO PC DIRECTORY This allows the user to select the source of the data to be transferred, either the PipeHawk

(PH), or the Client PC (PC). There is only one data directory upon PipeHawk. Additionally, by going to the PC directory, it is possible to select the destination directory on the PC where the PipeHawk data will be transferred. Below the directory selection is a list of the files in the selected directory, and at the bottom of the display for information purposes the current directory employed in the Client PC is indicated. The current directory is the destination where PipeHawk data will be transferred. 7.2.2 Selecting the Client PC to Accept Data Press Key 1 OR Press Key 2 Press Key 3 Move > symbol to line reading GO TO PC DIRECTORY This enters the above selection and allows the operator to access the Client PC from PipeHawk.

All the chosen data sets (highlighted by an asterisk) are copied from the PipeHawk hard disc to the chosen hard disc and directory on the Client PC. PipeHawk plc 2003 Page 34 PipeHawk Operators Manual 100049000-C 7.3 Transferring Data from a Client PC to PipeHawk This procedure is essentially very similar to that described above, but the data is transferred in the opposite direction. The requirement for this procedure arises when archived data needs to be reprocessed. Preparations for this data transfer are made in the manner described in section 7.1, with the PipeHawk being turned off to make the cable connection. PipeHawk is then turned on. A double click on the Transfer icon on the Client PC ensures that this machine is ready for the transfer. 7.3.1 Access the Data Transfer Menu from the Main Menu Press Key 6 The Data Transfer Menu is accessed allowing the Client PC and PipeHawk to recognise each other and to communicate. 7.3.2 Select the Client PC to Allow Access to the Required Data Press Key 1 OR Press Key 2 Press Key 3 Move > symbol to line reading GO TO PC DIRECTORY This confirms the above selection 7.3.3 Selecting the Client PCs Data Storage Device
