Isolating Cables:
To isolate the tone source in the cable bundle or at the patch panel,
do the steps as described in the previous section of "Locating
Cables".
1.
Strip the cable's shield to a length of between 30 to 45
centimeters and divide the wires into two parts. Do the
wire separation 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.
2.
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.
3.
Repeat the steps of 6 and 7 to isolate the bundled cables.
Caution
•
If you cannot locate the MT-7028 signal on 2-conductor
cables, the cable may be shorted or opened. Use the
Continuity Test (Fig. 8) to check for shorts or opens on
coax and non-terminated cables.
