The RMO-G Series of micro ohmmeters generate a true DC ripple-free current with automatically regulated test ramps. During testing the RMO-G units ramp with increasing current before measuring and decreasing current post measurement. This eliminates magnetic transients. This series is equipped with thermal and overcurrent protection. The RMO-G series can cancel electrostatic and electro-magnetic interference in HV electric fields by using efficient state-of-the-art filtration techniques facilitated by proprietary software and hardware.

RMO-G instruments can save up to 500 measurements within their internal memory. All measurements are time and date stamped and can be analysed using proprietary DV-Win software. Communication between the RMO-A and a PC is through USB connection (standard) or an RS232 cable (option). Bluetooth communication interface is also an available as an option.

DV Power provides a 3-year warranty on all test instrumentation. This is a guarantee to our customers that they will receive the highest quality test equipment on the market.
