5.9.2 Multi-transmitter operation – identifying cores in a multicore cable
Identifying cores in a multicore cables is possible in the voltage mode (Fig. 35), current mode and
voltage-current mode (Fig. 34). Approaching the receiver closely to the cable core improves the preci-
sion of indications based on the code signal.
In the multi-transmitter operation, each transmitter should be set with a different code of the
transmitted signal, choosing from the four available codes: A, B, C, D.
In the voltage mode, the cores that are not connected to the transmitters should be grounded (Fig.
35). In order to achieve clarity in identifying cable cores, use the contact probe connected to the re-
ceiver.
In the current mode, the proximity of cores may cause an incorrect reading of the transmitted
code by the receiver and a wrong identification. Increasing the selectivity may be achieved by using a
non-contact probe or by unambiguous identification of cores by C-8 measurement clamps.
