Page 3: Introduction
The depth of buried cables or sondes may also be displayed. Note: For more detailed locating instructions and advanced locating techniques, ask your 3M sales representative or call 800/426-8688 for a free publication called Cable and Pipe Locating Techniques. -
Page 4: Initial Receiver Configuration
INITIAL RECEIVER CONFIGURATION Display depth units (inches, feet and inches, or centimeters) may be changed while holding and pressing . For each press, one of three units will display. To change the passive Power frequency, press and hold then press to toggle between 50 or 60 Hz as displayed in the lower left corner of the display. -
Page 5: Transmitter Battery Test
TRANSMITTER BATTERY TEST To test the Batteries, press and hold . Listen to the tone and watch the display. • solid tone and 'OK' indicates batteries good; • beeping tone and 'LO' indicates batteries low; • no tone and '- -' indicates replace batteries. Note: The battery test indicates battery condition for normal output levels. -
Page 6: Locating A Buried Cable
LOCATING A BURIED CABLE Transmitter Setup Perform a battery test and then connect the Transmitter using one of the three methods below to put tracing signal on a cable. Note: Key descriptions can be found inside the Transmitter lid. DANGER! Voltage greater than 240 volts will damage equipment and cause personal injury and death. -
Page 7: Direct Connect Method
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. - Page 8 Press to select Trace mode. Press again to select one or all of the four frequencies. The display will alternate between displaying the selected frequency and the output signal current. It is best to choose the lowest frequency for direct connect with far-end ground and a high frequency for direct connect with no far-end ground.

Page 9: Dyna-Coupler Method
Dyna-Coupler Method Cable Path 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 turn Transmitter on. -
Page 10: Induction Method
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. Press again to select either 33 kHz or 200 kHz. For greater tracing range, select high output level by pressing Note: If the Receiver is less than 50 feet from the Transmitter, it can pick up signal through the air. -
Page 11: Receiver Setup
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 power frequency (see section on Selecting Passive Power Frequencies on Page 12) for passive locating; otherwise, select the same frequency as the Transmitter. -
Page 12: About Trace Modes
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. -
Page 13: Selecting Passive Power Frequencies
Selecting Passive Power Frequencies 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. -
Page 14: Determining Cable Depth And Current
DETERMINING CABLE DEPTH AND CURRENT Place the Receiver Antenna on the ground directly above the cable with the handle parallel to the path. Press and the display will indicate the cable depth and relative current . Current is displayed in the lower left corner of the display. -
Page 15: Using Current Indications During Locating
Using Current Indications During Locating Both the Transmitter and Receiver will indicate cable current. These current indications will help to select a trace frequency, identify the correct cable and troubleshoot the set up. When using the direct connect method, the Transmitter output current number is displayed. -
Page 16: Locating An Active Duct Probe (Adp)
LOCATING AN ACTIVE DUCT PROBE (ADP) Press to turn the Receiver on. Press to select the 33 kHz frequency. Press to select the Peak mode . If you find that the received signal is too weak in this mode, try the Special Peak mode. To select Special Peak mode: From Peak mode press and hold then press to toggle between Peak and Special Peak modes. -
Page 17: Locating Ems Markers
LOCATING EMS MARKERS EMS markers may be detected and located using either the 3M Dynatel ™ 2205 or 2206 EMS Marker Locating Accessory. To attach the accessory, slide the Receiver horizontally into EMS Marker Locating Accessory mounting slot. Make sure the locking button holds the Receiver securely in the slot. -
Page 18: Toning Aerial Faults
TONING AERIAL FAULTS Transmitter Setup Perform a battery test; then with the Transmitter off, plug the direct connect cable into the front panel jack. If fault is a shorted pair, connect Red clip to tip and the Black clip to ring. If the fault is a cross (two pair involved), connect the Red clip to crossed conductor of one pair and the Black clip to the crossed of the other pair. -
Page 19: Cable Or Pair Identification
CABLE OR PAIR IDENTIFICATION Transmitter Setup Transmitter setup is the same to identify cables or pairs, however, Receiver setups are different. Perform a battery test; then with the transmitter off, connect the Dyna-Coupler to the Transmitter front panel jack using the coupler cable. -
Page 20: Pair Identification Receiver Setup
PAIR IDENTIFICATION Receiver Setup Press to turn the Receiver on. Press to select Tone mode Connect the inductive probe to Receiver accessory jack using probe cable. Press to select the highest toning frequency (200 kHz). Insert Probe into the bundle of pairs (or group, if known) and press Next, divide the pairs into two bundles and insert the Probe into each of the bundles and observe the numeric display. -
