By always using it before starting working on an already existing system (which the operator therefore does not know well) and at the end of the job, this device will guarantee the necessary safety to both operators and users of the electric systems! Thanks to its small size, this device offers many operating opportunities. M73 is also used to test the safety of electric system; it s therefore capable of measuring non-trip earth resistance, carrying out tests on RCDs type A and AC and measuring Insulation and Continuity. At the end of the test, the device shows all results with the indication of compliance or non-compliance with the standards with simple symbols di OK or NOT OK.
