5.1.3 Locating the cable breaks
ATTENTION:
-
The circuit must not be live.
-
The cables that are not used, must be connected to the auxiliary ground (as seen in the figure
below).
-
Connect the transmitter to the cable connection and to the auxiliary ground.
The transition resistance of a cable break must be higher than 100 k
Ω.
Note during the tracking of cable breaks in multicore cables, that all the remaining wires in the shielded
cable or conductor must be grounded properly. This is required to avoid cross coupling of the supplied
signals (through a capacitive effect on the output terminals). The tracking depth for shielded cables and
conductors is different, as the individual wires in the shielded are looped around each other.
The ground connected to the transmitter can be an auxiliary ground, the ground of a grounded socket or a
properly grounded water pipe.
During the tracing of the cable, an abrupt drop of an incoming signal at the receiver takes place at the
point of interruption.
Set the transmission power in order to adapt it to different search radii.
The target position can be located accurately by using the manual mode and adjusting the sensitivity.
