DRM-1A - Digital micro-ohmmeter (1Amp)
2Pages

High precision digital micro-ohmmeter 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. ADVANTAGES Much lighter and handier than other equip- ment in its category Shock resistant, it is 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 Many accessories are available for your application such as measurements on very small surfaces 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 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-1A can be used in spite of the presence of intense magnetic fields. APPLICATIONS Quality control of smelting parts OPERATION The DRM-1A is suitable for both laboratory and field applications. 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-1A is shock resistant and suitable for many applications.
