DRM-40 PORTABLE MICRO OHMMETER
Portable Hand Held Digital Micro ohmmeter

DRM-1A Micro-ohmmeter
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.

 

  • Quality control of the smelting parts

  • Control of the mechanical joints
    and of the joints welded at high voltage

  • Control of the exothermal joints (Caldwell)

  • Control of the electrodes for the aluminum plants

  • Inspection of the contacts, the circuit 
    breakers and the power fuses

Operation

The DRM-1A 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.
