The MMR-620 Series meters are professional portable instruments for measuring very low resistances. Due to their special measurement algorithm they can be used for both resistive and inductive type of a specimen that makes MMR-620 a perfect instrument for electricianstesting electrical junctions, motors and power transformers windings.The results can be stored in the internal memory and send to a computer via serial interface. A quick PASS/FAIL test function with results displayed and acoustically indicated simplifies measurements considerably. The MMR-620 meter can also be used for testing the quality of the junctions in a production process via the interface.
