OPERATION FUNCTION
Cable / Wire Tracing
1. 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 un-terminated 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 connectors directly into the
matching cable connectors.
2. Set the tone generator power switch to the TONE position.
3.
On the amplifier probe, press and hold the side on/off switch.
4. Hold the insulated probe tip against the wire in question to pick up the signal
generated by the tone generator.
5. Rotate the volume/sensitivity control on the top of the probe for the appropriate
level and sensitivity to identify and trace the wire.
6. The tone will be the loudest on the wire(s) connected to the tone generator.
Note:
A headphone jack is located on the bottom of the probe.

Telephone cable identifying line condition
•
Switch the tone generator to the OFF position
•
Connect the red test lead to the RING side and the black test lead to the TIP side.
•
The LED will indicate line condition by:
GREEN = CLEAR, OFF = BUSY, Flickering YELLOW = RINGING

Continuity testing
•
Connect the test leads to the wire pair under test.
•
Switch the tone generator to the CONT position.

The LED will glow bright GREEN for a low resistance or continuity. The LED will
glow less brightly as the resistance increases and will extinguish at approximately
10,000ohms.
