CMW Overview - 4 Item 3. Antenna 2450GR Operators Manual Overview Notes The 2450GR scans and records both frequencies simultaneously at all times. Description Digital radar transmitter/receiver that uses two frequencies to detect buried pipes. High frequency (700MHz) has shallow penetration. Best in conditions with good radar conductivity, such as ice, sand, concrete, or rock. Low frequency (250 MHz) has broad, deep penetration. Better in conditions with poor radar conductivity, such as clay, salt, or wet soil. 4. Battery Provides 12V DC to control unit. 5. Wheel position sensor Measures the distance traveled by the cart. 6. Control Unit Receives data from the antenna and the wheel position sensor and translates it to the tablet PC. Recharge when battery drops below 10V, or as indicated by acquisition software. Located in the left rear wheel. 7. Battery Charger To recharge battery, connect charger to battery. Allow about 3 hours for battery to charge. CMW 2450GR Operators Manual Intended Use Intended Use Overview - 5 The 2450GR is a ground penetrating radar system that detects metallic and non-metallic pipes and cables buried underground. Following standard radar principles, the 2450GR uses a high performance electromagnetic sensor equipped with electromagnetic transmitters and recievers to identify underground utilities and transmit the location data to a portable computer where specialized software maps the location site. The unit is designed for operation in conditions typically experienced in earth moving and construction work environments. Provisions may be required to operate in extreme temperatures. Use in any other way is considered contrary to the intended use. The 2450GR should be used with genuine Subsite Electronics components. It should be operated, serviced, and repaired only by persons familiar with its particular characteristics and acquainted with the relevant safety procedures. Any changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. This equipment is sensitive to the presence of external electromagnetic fields, which may reduce its performance.

Determine site accessibility. Determine space available for cart. Gain permission to access pedestrian zones, interrupt traffic flow, etc. Observe traffic levels. Observe presence of parked cars. Observe presence of architectural obstacles. Inspect Visually Make a visual check of the site for signs of buried cables such as:

recent trenching buried cable markers overhead lines that run down the pole and underground gas meters valve sights drains or manhole covers Acquire Utility Maps Various companies produce technical maps of existing utilities. While some maps may be very generic, they are an important tool for gathering and interpreting data at the survey site. The maps provide general schematics of the type and position of the utilities managed or constructed by those companies. Request maps by contacting the utilitys cartographic or planning office. Specify the street names and areas of interest. Request maps well in advance of the actual survey. Types of utilities to consider are:

public street lighting low, medium and high voltage electric cables water supply gas telephone cables sewers CMW 2450GR Operators Manual Setup Setup 1. To open cart, remove pin (1), rotate handle

(2) to upright position, and insert pin into slot. Prepare - 31 2. To adjust height, pull knob (1) and raise or lower the handle (2) to desired height. Release knob to engage pin. CMW Prepare - 32 3. To attach computer to cart, align velcro strips on bottom of computer with velcro strips on cart. 4. Connect network cable from control unit to computer. 2450GR Operators Manual Setup 5. To lower antenna into scan position, pull rubber keeper (1) until it is free from pin (2). CMW 2450GR Operators Manual Check Battery Status Check Battery Status Control Unit Prepare - 33 Check battery status before each use, after each battery change, and as desired during operation. In normal conditions, battery lasts about 12 hours. To check 1. Connect control unit to battery. 2. Check battery status:

Control Unit If battery has greater than 10V, indicator on control unit will light. Software Check battery status indicator. If indicator is green, battery is fully charged. If indicator is yellow, battery is semi-charged. If indicator is red, battery needs recharged. If indicator is not lit, check the cable for a good connection or recharge the battery. To recharge battery If the battery runs down, 1. Shutdown unit. 2. Connect another battery. 3. Restart the system. Connect the discharged battery to the battery charger. It takes about 3 hours to recharge the battery. Tablet PC Check battery status before each use and after each battery change. See PC manufacturers instructions for more information.

Launch Acquisition Software The 2450GR software allows scan data to be acquired, saved, and viewed directly in the field. 1. Set the control unit power switch to ON. 2. Turn on the tablet PC. (See manufacturers instructions for more information.) 3. Click the 2450GR icon to launch the software. 4. Monitor progress of software self-tests. If one or more self tests fail:

Check that the control unit power switch is set to the ON position. Verify that the 2450GR battery is fully charged. Verify that the tablet PC battery is fully charged. (See manufacturers instructions for more information.) Check all cable connections. Calibrate System IMPORTANT: For an accurate survey, calibrate the system at the start of a scan and any time ground conditions change, for example, when moving from grass to concrete, or from concrete to asphalt. To calibrate, open the Radar Setup Window is open:

1. Press START CALIBRATION. 2. Push the cart a short distance, 10-15 ft (3-5 m). The unit will calibrate and automatically save the processing parameters and open the Acquisition Selection Window. 3. Enter a job name in the text window and press NEW ACQUISITION. IMPORTANT: Once a new survey is named a data file is created and saved in the C:\2450GR\mission directory. All files containing acquired data will be stored in this directory. To skip calibration, press SKIP CALIBRATION. Note: If you skip calibration, you will only be able to view pre-existing acquisition maps. CMW 2450GR Operators Manual Scan Scan Acquire Scan Data Ensure that the New Acquisition Window is open. 1. Press START SCAN and push or pull the cart to acquire survey data. Note: The 2450GR can be either pulled or pushed to acquire survey data;

however, the entire acquisition must be conducted in the same direction. Follow a grid pattern to scan the survey area. 2. A radar map will appear on the computer display. Select Shallow, Deep, or Dual to set frequency viewing preference. Note: The manufacturer recommends viewing dual frequencies to best detect buried objects. 3. Watch radar map for signs of buried objects, which appear as hyperbolas on the radar map. Operation - 37 CMW Operation - 38 Mark Objects 2450GR Operators Manual Scan 1. When a hyperbola (1) is appears , move the cart in the opposite direction. A vertical white line (2) will display on the radar map. Move the cart until the white line is in the center of the hyperbola. 2. Mark the ground: Use spray paint to mark the location on the ground (shown). A red arrow on the side of the antenna corresponds to the white line on the radar map. 3. Mark the acquisition map:

Using the Up/Down buttons (4), position the red horizontal cursor (3) at the top of the hyperbola. Press the MARK button (5) to open the Mark Window. (See next page.) CMW 2450GR Operators Manual Scan Record Target Information Operation - 39 Record target information during a survey, or at a later time. See Acquisition Editing Window on page 25. 1. Press the FITTING button (2), then Use the UP and DOWN buttons (3) to adjust the curve to match the hyperbolas. This sets the correct propagation speed to accurately calculate object depth. 2. Select an icon to label the type of pipe you suspect. IMPORTANT: The GPR system does not identify what type of pipe or cable is buried. This information can be determined from opening manholes or consulting technical maps. 3. Press GROUND TRUTH SKETCH (1) to note exact depth of cable or pipe, if known. This information is obtained from outside sources such as technical maps, by opening manhole covers, or by potholing. 4. To continue scanning, move 2450GR in original direction.
