DANGER! Check for stray voltage before attaching Transmitter. Voltage greater than 240 volts will damage equipment and cause personal injury and death. Follow standard procedures for reducing the voltage. WARNING! Potential for electrical shock exists when handling connecting cables while the Transmitter is in the TRACE, FAULT or TONE modes. Turn the Transmitter off before handling connecting cables. Page 4 Direct Connect Method Make sure the Transmitter is off. Plug the direct connect cable into the front panel jack. Connect the Black clip to the ground rod. Place the ground rod in the earth perpendicular to the suspected cable path. If necessary, extend the black lead with the Ground Extension Cable. Remove the ground bonding and attach the Red clip to the shield. Note: Never attach or remove the direct connect cable from the Transmitter front panel jack while the red and black clips are connected to a cable. Press to turn the unit on and select Continuity Test (solid tone=good ground; beepingtone=usable ground; no tone=poor ground or no far-end ground). Both LEDs light continuously during the continuity test. Press to apply Tracing signal and select the desired frequency: 577 Hz for direct connect with far-end ground; or 33 kHz for direct connect with no far-end ground. LED indicates frequency selection. (This key can also turn the unit on.) Press to change output level. Choose Normal output (flashing LED) for locating short to moderate distances using direct connect method. Use High output (solid LED) for long distances and deep cables. Transmitter setup is finished, now go to LOCATING A BURIED CABLE -Receiver Setup (Page 8). Page 5 Dyna Coupler Method Connect the Dyna-Coupler to the Transmitter front panel jack using the coupler cable. Clamp the Dyna-Coupler around the cable below any bonds just before the cable enters the earth. The jaws of the coupler must fully close. Press to apply Tracing signal and select the 33 kHz frequency. LED indicates frequency selection. (This key can also turn the unit on.) Select high output level by pressing . Transmitter setup is finished, now go to LOCATING A BURIED CABLE - Receiver Setup (Page 8). Page 6 Induction Method Place the transmitter on the ground over the target cable with the lid hinge in line with the cable path. Press to turn the transmitter on and select the 33 kHz frequency. LED indicates the frequency selection. For greater tracing range, select high output level by pressing . Transmitter setup is finished, now go to LOCATING A BURIED CABLE - Receiver Setup (PAGE 8). Page 7 LOCATING A BURIED CABLE Receiver Setup Note: Key descriptions can be found on the side of the Receiver. Press to turn the Receiver on. Press to select the 50/60 Hz power frequency (see section on Selecting Passive Power Frequencies Page 9) or LF for passive locating; otherwise, select the same frequency as the Transmitter. Note: The Receiver is automatically set to Special Peak mode when LF is selected. No other modes are allowed in LF frequency. Press to adjust the speaker volume as needed: off, normal, high, or high-expanded. The high-expanded setting causes the audio to cut off as the antenna moves away from the cable. Note: While tracing cables, keep the Receiver handle in line with the suspected cable path. To select Special Peak mode, press and hold the press . While in this mode, the peak flag will flash. Note: Peak or Special Peak mode may require re-setting the Receiver gain. Press when the bar graph remains either fully open or fully closed. Page 8 About Trace Modes Peak: In this mode, as the antenna crosses the cable, the Receiver speaker volume increases to a maximum and the bar graph fills from both sides toward the middle. As the antenna moves off the cable path, the speaker volume decreases and the bar graph opens. Peak with High-Expanded: While in Peak mode, press to select High-Expanded (the highest setting). Speaker response is cut off as the antenna moves away from the cable. Special Peak Mode: This mode will increase the signal sensitivity of the Receiver when the signal is too weak for normal tracing. Use special attention when using this mode because it is more susceptible to congestion than the normal peak mode. To select Special Peak mode, press and hold then press . While in this mode the Peak flag will flash. Note: While tracing cables in any mode, keep the Receiver handle in line with the suspected cable path. See section Initial Receiver Configuration (Page 3) to set the power frequency to 50 Hz or 60 Hz. The Receiver can be tuned to locate 3 different harmonics of the chosen power frequency. H50 Hz or H60 Hz (high harmonic): Best for general locating of passive power. L50 Hz or L60 Hz (low harmonic): Works best on primary power cables. May be used when high harmonic is weak or erratic. 100 Hz or 120 Hz: For locating rectified AC power signals, often found on pipelines using impressed current cathodic protection. When a Power frequency is selected, the H...
