4)
Continue following the highest reading until the signal starts weakening. This is the point of the
fault as the signal flows to ground instead of continuing strongly down the shorted conductor.
Reduce the sensitivity range and use the nose of the receiver to pinpoint the source of the fault.

Higher Voltages
When using the alligator clips to attach the transmitter to live voltage that is greater than 120 VAC use
the following method. Install the alligator clips to the ends of the 3 foot leads. Do not plug them into
the transmitter. Using appropriate PPE procedures, attach the alligator clips to the live conductors.
Next, plug the safety leads into the terminals on the transmitter, polarity is not important. Now turn
the transmitter on and note if the line energized light illuminates. Proceed with your tracing or fuse
or breaker identification. To disconnect, turn the transmitter off, and remove the terminals from the
transmitter. Next, using appropriate PPE procedures disconnect the alligator clips from the energized
conductors.

Sorting Bundled Wires
Applications include identifying a specific circuit amongst several circuits in a filled conduit, sorting
wires in a wire harness, identifying coax cable and twisted pair cable in a termination box.
1) Connect the transmitter to the circuit to be traced and power it on.
a) Clip one test lead to the known end of the wire to be traced or identified.
b) Clip the other test lead to a remote return path.
2) Turn on the receiver and set it to the least sensitivity ( ).
3) Go to the other end of the wire run and sort out the individual wire using the nose of the receiver.
a) If the signal is too strong, separate the wires more from the bundle when testing.
b) If the signal is too weak, then increase the sensitivity range on the receiver and repeat step #3.
4) Continue sorting until the wire with the highest reading is identified.
