3.5 Locating of line interruptions in the plastic-sheathed cable
(one-pole application)
Note:
When locating of line interruptions, the circuit must be dead; All lines which are
not required must be connected to the auxiliary ground in accordance with figure 8;
Connect transmitter to one lead and to an neutral according to figure 5; and Carry
out this example as described in the application example.
The ground connected to the transmitter should
be earth from an earthed socket or a water
pipe which is properly earthed. When tracing
line interruptions in multicore cables, not that
all remaining leads in plastic-sheathed cable
or conductor must be grounded in accordance
with the regulations. This is required to avoid
crosscoupling of the fed signal (by a capacitive
effect to the source terminals). The tracing
depth for sheathed cable and conductors are
different, as the individual leads in the sheathed
cable are twisted around themselves. The
transition resistance of a line interruption must
be higher than 100 kOHM. The verification of
resistance can be carried out by any multimeter.
The switching with button 4 from “LEVEL I” to “LEVEL III” the sensitvity of Distance
is increased up to factor 5.
Tracing depth max. 2 meters.
Setup: manual mode, minimal sensitivity
