The Micro Ohmmeters – RMO series instruments are designed for contact resistance measurement of non-inductive test objects. RMO instruments are based on state of the art technology, using the most advanced switch mode technique available today. RMO generates a true (ripple free) DC current with automatically regulated test ramps. During the test RMO ramps with increasing current before measuring and decreasing current after the measurement. This approach eliminates magnetic transients.
