The Digital Microohm meter is a precision instrument, which is extremely suitable for measurement of low value resistance.
The instrument uses state of art technology for measurement of low values of resistances. The measuring technique eliminates errors caused due to resistance in the connecting leads.
The instrument uses precision low drift integrated circuits to ensure stability of measurement over widely changing conditions.

The MPK-204 high-current micro-ohmmeter is a
truly portable, microprocessor-controlled instrument, used to accurately
measure very low contact resistances of breakers and switches, busbars,
transformer and motors winding and motors, etc, with test current from 1 mA
to 200 A. It employs the Kelvin-type measurement to avoid measurement errors
caused by test leads and their contact resistances. Readings are shown in
the alphanumeric display with up to 4 � digits resolution. It allows to
measure resistances up to 200 O, with a resolution down to 0,1 �O. Using its
internal rechargeable battery, measurements with up to 10 A test current may
be carried out without connecting the equipment to the main supply. Powered
by the mains supply, it allows to measure with any test current up to 200 A.
