Micro Ohmmeter RMO400A

RMO400A is a Micro Ohmmeter based on a state of the art technology, using the most advanced switch mode technique available today. RMO400A generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO400A 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 RMO400A 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 RMO400A 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 RMO400A 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.
