Cable/Wire tracing
CAUTION:
Do not connect the tone generator in the TONE position to any wire or cable
with an active circuit of more than 24VAC.
-
Connect the tone generator to the cable
a) For cables terminated at one end, connect the red alligator clip to a wire and the black alligator clip to equipment ground
b) For unterminated cables, connect the red alligator clip to one wire and the black alligator clip to another wire.
c) For cables with modular connectors, plug the RJ11 or RJ45 connectors directly into the mating cable connectors. -
Set the tone generator power switch to the TONE position.
-
On the amplifier probe, press and hold the side on/off switch.
-
Hold the insulated probe tip against the wire in question to pick up the signal generated by the tone generator.
-
Rotate the volume/sensitivity control on the top of the probe for the appropriate level and sensitivity to identify and trace the wire.
-
The tone will be the loudest on the wires connected to the tone generator.
Note: RJ11 tests are performed on one pair only and RJ45 tests are
performed on pins 4 and 5.
Note: A headphone jack is located on the bottom of the probe.
