Conditions:
1. The current circuit must not be live.
2. All lines not being used must be connected to the auxiliary ground as
shown in the figure.
3. Connect both transmitters as shown in the figure.
4. Proceed as described in the application example.
The ground connected to the transmitter and to the wires not being used can be as follows:
an auxiliary ground, an orderly connected ground contact of a home office socket, or an
orderly grounded water pipe.
Please make sure during line interruption locating in multi-wire shielded conductors and
cables, that all remaining wires are orderly grounded. This is required to avoid inductive
disturbance (by capacity coupling). The locating depth for shielded conductors and cables
varies, as the individual wires within the shield are twisted. The transition resistance of a line
interruptions must exceed 10kOhm. The determination of the transition resistance can be
carried out using a multimeter.
Systematically circle the interruption by changing the sensitivity.
