Operation
To use the PowerTone System:
1
Connect the tester to a wire pair; then turn on the
tester.
2
At the other end of the cable, use your tone probe
to find the wire pair by probing for the pair with
the loudest tone.
3
Short the wire pair together, then release the
short.
•
If you DO NOT hear a change in the tone,
then you have not found the correct pair.
•
If you DO hear a change, then you have
POSITIVE CONFIRMATION that you have
found the correct pair.
Note
The tone is not audible on the tester’s beeper.

1. LLLL = the length to the fault.
2. An open may be a break in a wire or a separation
between the wires in the pair. If one wire in the pair
separates from the other wire for 1 ft (30 cm) or more,
the tester indicates an open at the separation.
