High Precision Digital 1A Micro-ohmmeter Model:DRM-1A
The DRM-1A™ is a lightweight and portable micro-ohmmeter designed to measure very low resistances from 1 μΩ to 200 Ω. It is the most accurate in its category.
The DRM-1ATM uses a four-pin resistance measu- rement 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 voltage 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-1ATM can be used in spite of the presence of intense magnetic fields.
