1. Description
The MPK-256 micro-ohmmeter is a portable, microprocessor controlled
instrument, used to accurately measure very low contact resistances of
breakers and switches, busbars, transformers and engines windings, etc,
with test currents from 1 mA to 10 A.
Microprocessor controlled
Kelvin architecture (four-terminal method)
Digital reading, alphanumeric display
Up to 4½ digits readings
Powered by rechargeable battery
1 µΩresolution
2000 Ωmaximum reading
Up to 10 A current
Remote control through an Android app
1.1. Operating principle
This device uses the Kelvin Bridge architecture, with four terminals,
avoiding testing leads resistance to cause error during measurement. The
operator may choose test current and the reading is obtained by
comparison through internal high-stability standards. The result appears
in the alphanumeric display that is very easy to read.
