This Wire Tracer and Circuit Tester - including a sender and a detector - is designed to identify and trace wires or cables without damaging the insulation. 

Use as Circuit Tester

Connect two alligator clips to the ends of the wire to check if resistance exists. If yes, the wire could be a short or open circuit. You can use the Wire Tracer function to locate the problem.

Use as a Wire Tracer

By sending a signal down the wire being tested, you can trace the wire with the detector probe. An audible tone will increase in volume as the probe gets closer to the wire. Even when you have a bundle of wires, you can still find the wire you wish to trace with the help of the volume knob.

For telephone lines, the Wire Tracer and Circuit Tester can identify Tip and Ring lines and determine the status of the line - clear, busy, or ringing - making it more convenient to maintain telephone lines.
