Press only when a marker is detected and the signal is too strong. To search for a new marker, reset the Receiver gain to the initial setting by turning its power OFF and back ON, or pressing and then re-selecting the Peak mode. Refer the EMS Marker Locating Accessory operating instructions for further information. Page 17 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. If the fault is a ground, connect the Red clip to the faulted conductor and the Black clip to ground. Press to turn the Transmitter on in the Ohms mode to verify the fault. Press twice more to select the Tone mode . Press to change the high output level. Receiver Setup Press to turn the Receiver on. Press to select Tone mode . Connect a toning coil to the Receiver accessory jack. Press to select the low toning frequency (577 Hz). Move the toning coil along the cable and find a peak signal then press to adjust the Receiver gain. Press to adjust the speaker volume as needed. Follow the cable with the toning coil. An aerial fault is located at the point where the tone stops or drops off sharply. Page 18 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. Note: Cable Identification requires two Dyna-Couplers: one at the Transmitter and one at the Receiver. Clamp the Dyna-Coupler around the cable or both and tip and ring of a pair and make sure the jaws fully close. Press to turn the Transmitter on and then twice more to select the Tone mode . Press to change the high output level. CABLE IDENTIFICATION Receiver Setup Press to turn the Receiver on. Press to select Tone mode . Connect a second Dyna-Coupler to the Receiver accessory jack using the earth frame cable or another coupler cable. Press to select the highest toning frequency (133 kHz). Check the first cable in the group by clamping the Dyna-Coupler around the cable. Press and observe the numeric display, which is relative signal strength. Remember the number and continue by clamping the Dyna- Coupler around the next cable in the group. If the signal strength is greater than the previous observation, press . If the signal strength is less than before, ignore it. After checking all the cables in the group, the cable with the highest reading is the one being identified. Page 19 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 (133 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. The bundle with the highest reading will contain the target pair. Continue by dividing the bundle with the target pair into two parts and checking each part for the highest signal. In this way the target pair will be isolated.
