Description
Measure motor winding resistance and other low resistances
Perform precise tests of objects of resistive and inductive nature
using one instrument - small resistance meter Sonel MMR-630.
We present a versatile small resistance meter that provides very
high measurement accuracy. The measurement resolution is 0.1 µΩ.
The MMR-630 model enables measurements of objects of resistive as
well as inductive nature, such as transformers and motors. This
is due to the large measurement current for the individual subranges
and the corresponding operating modes. When testing objects
of a resistive nature, rapid measurement (3 seconds) is applicable.
When testing inductive objects, extended measurement is used
(there is also the possibility of a shortened mode with a slightly
lower measurement accuracy).
The MMR-630 has been enhanced with special functions that allow it
to be used also in the production cycle for serial measurements,
for example, during the inspection of large batches.
Product features
MMR-630 microohmmeter enables accurate measurements of both
connections resistance (welded, soldered, bolted) and winding
resistance of electrical motors.
- Measurements of objects resistive in
nature:
- welded and soldered connections,
equipotential bondings, earthing conductors,
- contacts, welds of rails, conductors and
cables,
- measurement according to the four-lead
method.
- Measurements of objects inductive in
nature:
- motor windings,
- low-resistance coils.
