Locating network, telephone and multimedia cables, and individual
wires
Connect the adapter cable or cable to be located to the sender and switch the device to
SCAN mode. If necessary, connect the sender to a network or telephone socket (see Fig.
b). For measurements using the cable terminals, connect the red terminal to the cable to
be located and connect the black one to earth (earthing conductor or shielding). Then use
the receiver to search for the connected cable. See also Tip 2.
Tip 3: To locate the cable more efÖ ciently, gradually reduce the receiver signal volume
using the control (14). The cable can be located by means of volume differences and is
indicated by the status LED (12) lighting up at its brightest or by the maximum signal
volume.
Tip 4: The best search results are achieved when the test prod (10) has a direct metallic
contact with the cable being located. This type of contact will produce a clearly audible
jump in the signal. You can also get stronger signals at the cable ends (Fig. c) or directly at
the individual wires (Fig. d).
Tip 5: Any interference that occurs (buzzing, etc.) can be reduced by earthing the return
conductor or shielding conductor in the test lead. Earthing by means of your own hand or
Ö nger may be enough, however.
Tip 6: Parallel supply lines may generate buzzing interference in the test lead. If the exter-
nal interference is too great, switch off the household power supply during measurement
if possible.
Tip 7: TV sockets in particular may contain Ö lters that have a negative effect on measure-
ments. In this case, remove the TV socket and perform the measurement directly at the
cable.

– The lead transmission signal that is fed in may be transmitted to other cables if
they are parallel to the lead over longer distances.
