Using the SmartTone Function
To use the SmartTone function to identify a wire pair:
1
Turn on the test set, then connect it to a wire pair
in the cable.
2
Make sure that the test set shows 0 VDC.
3
Press M, press D to put the flashing cursor next
to SmartTone, then press M, then press M
again to turn on the toner.
If there is voltage on the line, the display shows
SmartTone Volt Detect Lock Out,
and toner will not operate.
4
At the other end of the cable, use a tone probe to
find the wire pair that has the loudest tone.
5
To make sure you have found the correct pair, put
a short momentarily across the wire pair (Figure 4).
If the tone changes, you have found the correct
pair.
Notes
You cannot hear the tone on the test set.
