Cable fault locating, testing and diagnostic system for LV & MV & HV networks
The M32 is a minimised test and fault locating system for mobile integration with powerful extension options. It is built on the MX-platform that can integrate most modern test methods into an easy to operate and economic design without compromising safety or original measurement performance. The complete system and the plug-compatible extension modules are operated via central unified control unit. HV switching to test leads is semi-automatic and requires manual plug-over switching for high voltage testing and in case of multiple modules. Numerous additional available modules allow upgrading and customising the system to individual user requirements.
