Cable Fault Meter
-
A cable fault meter can locate open power cables, either live or dead (without current), with voltages up to 300 V. A cable fault meter can locate cables, circuits, short circuits and ground wires. To perform these functions, it is not always necessary to disconnect electrically sensitive devices or to disconnect the power from the cable which is being tested. Many cable fault meter devices can also locate ferrous and non-ferrous metals, wood and plastic with high degrees of accuracy.

Shorting relays on each channel enable UUT signals to be subjected to external user applied fault conditions or to be shorted to the adjacent signal in the same channel. Relays in line with the signal allow open circuit conditions to be simulated on either side or both sides of a channel signal pair. The switching topology of the 40-196 allows channels to be interconnected so that complex fault insertion systems can be constructed.
