The model M72 is an innovative portable device for measuring the insulation resistance and the continuity test of protective conductors according to VDE 0100 on civil electrical installations. It also acts as a TRMS multimeter (true rms value) and measuring device for determining the direction of the rotating field, making it ideal for checking electrical installations in accordance with VDE 0100 / VDE 0105.
With the M72, insulation measurements can be carried out with a test voltage of up to 500 V DC and the continuity test of the protective conductor (low-resistance measurement with> 200 mA). They are therefore used for tests according to VDE 0100 / VDE 0105 on electrical installations and for tests on industrial applications. Another function is the rotating field direction measurement with only one measuring line, the fault current measurement with external current clamp (with optional accessories) and an efficient TRMS multimeter function.
