RMO200A is a Micro Ohmmeter based on a state of the art technology, using the most advanced switch mode  technique  available  today.  RMO200A  generates  a  true  DC  ripple-free  current  with  automatically regulated test ramps. During  a test the RMO200A ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients. After the test current has been set, the automatic test procedure is started by pressing the Ω-button.  
The RMO200A instrument can store internally up to 500 measurements. All measurements are time and date stamped. Using the DV-Win software a test can be performed from a user’s PC, and the results can be obtained directly on the PC. Communication between the RMO200A and a PC is through an USB (as standard) or an RS232 cable (as an option). Using the DV-Win the result can be arranged as an Excel spreadsheet which can be later shown as a diagram and printed for a report.  The set is equipped with a thermal and an overcurrent protection. The RMO200A has a very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing a proprietary hardware and software

The full output is available from the RMO200A at 230 V Mains Supply. A reduced output is available from lower supply voltages.
