RJM Equipment Sales, Inc 360-828-5732 brianmoss@rjmcompany.comQuick Locating Guide for Radiodetection RD8000 and RD7000 Use Peak & Null: Compare the bar to the arrows to determine accuracy; trust the peak bar themost. “Max V” on “High” can increase the signal without increasing the frequency potentially increasingerrors. Automatic depth measurement: Rotate the compass to straight up and move side to side above the cableor pipe. Verifying depth accuracy: If the depth reading changes by the amount that you lift the locator, then it isaccurate. Place ground rod with no utilities between it and your utility. Double ended connection: For challenging locates, connect both leads from the transmitter with anextension lead to the utility.Choosing FrequenciesMatch the locator and transmitter frequencies. Use the lowest frequency that is strongenough. Lower frequencies are potentially more accurate. Higher frequencies arestronger. Check the mA display on the transmitter if direct connected to determine signalstrength: 10m A minimum, 20 – 30 mA typical. Common frequency choices:o Power cable with clamp: 33 Khzo Metal water mains: 33 Khzo Locatable rodders: 33 Khzo Tracer wire: 512 hz if grounded on other end, 33 Khz if not grounded on other endCable fault locating:1. Locate the cable2. Connect black lead to ground stake and red lead to faulted conductor3. Select transmitter frequency with A-frame picture4. Connect the A-frame cable to the locator and turn on locator.5. Hold green spike in front of the locator and follow the arrows.6. Check the whole cable. The numbers indicate the severity of the fault.Sonde / Camera Locating:1. Choose the same frequency as the sonde with sonde mode.2. Hold bottom of locator parallel to pipe or conduit.3. Locate minor and major center peaksPassive Frequencies Search then search again at 90 degrees to first pattern Power: locates most power cables with a load and utilities near power lines. Radio: finds most utilities. PASSIV: Power and Radio combined (RD8000 only) CPS: Locates most metal gas pipes, some water mains (DL, RD8000 only)
