52 C.A 6681 Cable Locater
Fig.12
Remarks:

The transition resistance of the line break must be greater than 100kOhms.

Note that, when breaks in multi-conductor cables are traced, all the other
wires of the cable or of the shielded conductor must be earthed. This is
necessary to prevent cross coupling of the applied signals (by a capacitive
effect) on the terminals of the source.

The earth connected to the transmitter can be a auxiliary earth, the earthing
terminal of a power outlet, or a correctly earthed water pipe.

When the line is traced, the place at which the signal received by the receiver
falls off suddenly is the location of the break.
Refine the detection by setting the power level transmitted by the
transmitter and the sensitivity of the receiver in manual mode.
