DRMTM Series are a lightweight and portable micro-ohmmeter designed to measure very low resistances from 1 micro-ohm to 200 micro-ohm. It is the most accurate in its category,
There are 3 types of DRMTM:
- DRM-1ATM – 1A micro-ohmmeter.
- DRM-10ATM – 10A micro-ohmmeter.
- DRM-40TM – 5A micro-ohmmeter.
DRMTM Series use 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. These instruments are equipped with a microprocessor which eliminates gaps and parasite voltages. The devices can be used in spite of the presence of intense magnetic field because of its unique filtering system.
Features:
- Uses the four point measuring method.
- Automatic current adjustment from 5mA to 1A (DRM-1ATM), 10A (DRM-10ATM), 5A (DRM-40TM).
- Automatic stop mechanism of the instrument in idle mode after 2 min.
- Automatic stop mechanism of the backlighting system after 30 seconds.
- The result display is easy to read.
- A set of standard connecting cables with alligator clips comes with the instrument.
Advantages:
- Much lighter and handier than other equipment in its category.
- Shock resistant, suitable for all types of applications: work site or laboratory.
- The LCD display is equipped with a backlight to allow work in any conditions.
- Weak current injection for applications that require small measurement contacts.
Applications:
- Quality control for smelting parts.
- Control of mechanical joints and high coltage welded joints.
- Control of exothermic joints (Cadweld®) (DRM-10ATM and DRM-40TM only).
- Control of electrodes for aluminum plants.
- Inspection of contacts, circuit breakers, and power fuses.
