Using Tone Mode
Tone Mode is used to trace cable runs and locate faults by sound.
Selection of this mode emits a cadence from the main tester through
the connected cable. The tone is detected by a tone tracer probe (sold
separately. Refer to the
Additional Accessories
section).
Note
: It may be impossible to differentiate between the tone
generated from the test pair and the sound emitted by
neighboring wiring pairs within the cable.
1. Connect one end of the cable to the main tester. The remote tester is
not used.
2. With the unit turned OFF, press and hold down the LENGTH/TONE
button for two seconds to enter Tone Mode.
3. To select a tone cadence, press the LENGTH/TONE button repeatedly
to step through the 4 cadence options: HI, LO, Hi-Lo1, and Hi-Lo2.
Stop when you reach the option you want.
The option you select determines the cadence sent from the main
tester, through the cable, and picked up by the tone tracer probe.
Note:
If you do not adjust the cadence, the main tester will default to
the last selected cadence.
4. Press the appropriate cable type button (voice, video, or data) to
select a cable for the tone signal.
5. Press the cable type button again to select different combinations
of pins to carry the tone signal. Each press of the cable type button
steps you through the cable’s wire pairs. The selected pin pair ap-
pears in the Wire Map. Figure 11 shows pin pairs 1 and 2 selected for
testing a data cable.
