DM-200 high-current micro-ohmmeter is a portable, microprocessor-controlled instrument, used to accurately measure very low contact resistances of breakers and switches, busbars, transformers winding and engines, and others with test currents from 1 mA to 200A.

Using its internal rechargeable battery, measurements with up to 10 A test current may be carried out without connecting the equipment to AC power. Powered by AC main power, it is able to measure with any test current up to 200 A.
