About the Tone Function
The tone function provides tone for pair identification.
The
unit can send tone for two hours before automatic
shut-off.
With the TONE key, you can apply precision tone to the
cable for
loss measurements. With the 965/965M, you
can also apply tone of any user-entered frequency and
amplitude
for loss or gain/slope measurements.
For the specific tone output of your test set, see Section
Three, “Specifications.”
Caution
If hazardous voltage warnings are displayed when the test set is
switched on or reset (or at any time during the testing
procedure) follow standard procedures for de-energizing and
discharging cables.
