The Lightest Micro-ohmmeter In The Industry
RMO-H
The RMO-H is a portable, battery-operated micro-ohmmeter based on state-of-the-art technology, using the most advanced battery mode and switching technique available today. The high-capacity Li-Po battery allows the generation of a ripple-free DC current of up to 300 A. The test current is user-selectable and generated in an automatically regulated test ramp. During the test, the RMO-H increases the current before the measurement and decreases it afterwards. This significantly reduces magnetic transients.
