Locating and Isolating Cables
Locating and Isolating Terminated UTP/STP Cables with MT-7068
Warning
• It is not intended to be used on
live
wires
with
a DC power source
(e.g.,
live
telephone lines), nor
will
it
work on wire pairs that are carrying AC signals.
Caution
• To locate and isolate cables using the 1KHz analog toning mode, please avoid interference sources like
electronic devices with adapter, induction coil, and motors nearby. White noise from MT-7068-R Probe
is normal when your Toner is near any of the interference. If you cannot locate the signal on 2-conductor
cables, the cable may be shorted. Please away from or turn off the electronic devices.
• The
position on the MT-7068 Toner and Probe lets you use the Probe to trace using an analog
1KHz tone. Use the Probe to isolate the tone source in the cable bundle or at the patch panel.
• It is not necessary to touch the Probe's tip to the cabling or patch panel when searching for the Toner's
signal.
• Make sure the black alligator clip of the Toner is connecting to the ground before use.
MT-7068 Toner provides two 1 KHz analog toning modes, one-note tone and two-note tone, for location and
isolating cables. Both toning signals are available at all connectors on the Toner.
