DRM-1A Portable Micro-ohmmeter.
DRM-1A Micro-ohmmeter. Measurement Range: 1µΩ to 200Ω. Current 1 Amp.
The DRM-1A micro-ohmmeter can be used to measure low resistances which vary from
1 micro ohm to 200 ohms. It is used for quality control of smelting parts, control of mechanical joints,
electrical connections, for inspection of contacts, circuit breakers, power fuses and more.

Advantages of the DRM-1A.
Shock resistant, it is suitable for all types of applications: work site or laboratory.
Its back-lighting liquid crystal display (LCD) enables it to be used in dark areas.
Weak current injection for applications that require small measurement contacts.
A variety of probes adapted to types of specific measurements are available as options.
The DRM-1A portable micro-ohmmeter 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-1A can be used in spite of the presence of intense magnetic fields.
