DRM-10A Micro-ohmmeter. Range 0.01 µΩ
to 200
Ω, Current 10Amps
The DRM-10A is suitable for both in-plant
maintenance and field. Resistance measurements are calculated
automatically. This equipment has become the number one choice for
industries, products engineers and manufacturers. Recognized as the
most accurate and easy to use on the market, the DRM-10A is shock
resistant and suitable for many applications.
The DRM-10A micro-ohmmeter can be used to measure very low
resistances
which vary from 0,01µΩ to 200Ω. This is the most accurate on the
market in its category.

The DRM-10A uses a four-pin
resistance measurement system which consists of injecting a current with
two cables connected at each end of the joint to be tested. Then, the
cables are installed which allow reading the tension on each side of
the part to be tested in order to measure the resistance.
This
eliminates any uncertainty linked to resistance of the contacts.
The
instrument is equipped with a microprocessor which eliminates gaps and
parasite voltages.
Thanks to its unique filtering system, the DRM-10A can be used in spite
of the presence of intense magnetic fields.
