Approach the receiver to the tested object in
order to determine whether it is a source of
alternating electric field.

5.9 Multi-transmitter operation
LKZ enables operation work with four transmitters at the same time. Each transmitter must be
synchronized with the receiver and have a specific code of the transmitted signal set to uniquely iden-
tify the transmitter (A, B, C, D). When it is necessary, the synchronization of transmitters with the re-
ceiver is carried out in accordance with sec 3.3.
The multi-transmitter operation of the system enables precise location of breaks in an electric sys-
tem and identify individual cores in the cable.
5.9.1 Multi-transmitter operation – locating breaks
The transmitters should be connected to two ends of an open circuit. Each of the transmitters
should be assigned with a specific code of the transmitted signal and the voltage mode set for the
transmitted signal. The place of detected break will be indicated on the receiver by changes in the re-
ceived signal code.
