MMR-620 / 630 OHM Meter
MMR-620 & MMR-630
Key Features:
-
The MMR-6X0 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-6X0 series perfect instruments for electricians testing 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.

Automatic or manual selection of measurement range (measurement of objects of inductive nature).
Selection of measurement mode adapted to the type of the measured object:
- fast measurement (3 seconds), for measuring objects of
resistance nature,
- extended measurement for measuring objects of inductive
nature (a shorter mode with slightly limited accuracy is
available); including automatic discharge after the measurement.
Choice of measurement mode depending on application (e.g. inspection of series of products):
- measurement in normal mode - triggered after pressing the
"START" button,
- measurement in automatic mode - the instrument awaits for
connecting all four test leads to the object, and then
automatically starts measurement with current flow in one
or two directions, and calculates the mean value of resistance,
- measurement in continuous mode - every 3 seconds, the
meter repeats measurement cycles with pauses (for objects
of resistive nature), or performs continuous measurement (for
objects of inductive nature).
Window mode:
- allows for setting the upper and lower limits for the measurement
result; exceedance of such a range is signalled acoustically.
Capability of performing measurements with interferences of values even five times higher than the measured signal.
