Mini cable fault locating and test system
for LV & MV networks

The M12 is a minimised test and fault locating system for mobile integration. It is used for troubleshooting, pre-locating and pinpointing of faults in complex LV & MV networks up to 12kV. Operation by one central control unit with menu guidance simplifies handling, accelerates operational choices and ensures safety compliance. Featuring a large colour screen, the system can display

measurement curves, test results and message codes simultaneously. Integrated full scale TDR capability in combination with the high voltage arc reflection mode (ARTi) will isolate and pre-locate low as well as high resistance faults with utmost precision. The extensive multi-dimensional safety system 6D complements this mini system to provide a compelling value proposition.
