Isolating Cables - Pro's Kit MT-7068 User Manual

Isolating Cables

To isolate the tone source in the cable bundle or at the patch panel, do the steps as described in the previ-
ous section of "Locating Cables".
6. Strip the cable's shield to a length of between 30 to 45 centimeters and divide the wires into two parts.
Do the wire dichotomy to isolate the cables to verify the signal of each part. If the beeper gets louder and
LED lights up, you have located the position you are looking for.
7. Adjust the volume control from high to low to enable looking for a more difficult to identify wire. Narrowing
the length from 30 to 10 centimeters will help to more accurately identify the wire pairs.
8. Repeat the steps of 6 and 7 to isolate the bundled cables.
Caution
• If you cannot locate the MT-7068 signal on 2-conductor cables, the cable may be shorted or opened. Use
the Cable Map Testing (Fig. 5) to test for shorts or opens on cables with RJ11 and RJ45 connectors. Use
the Continuity Test (Fig. 8) to check for shorts or opens on coax and non-terminated cables.
