MMO-40 resistance meter

MMO-40 resistance meter

The Meter MMO-40 is standalone device, designed to measure the circuit resistance of various components of electric equipment that completely deenergized in a wide range of measured values.

Measurements are taken at four-wire circuit scheme.


MMO 40 provides an output of measurement results on LCD display.
