RMO600A is a Micro Ohmmeter based on state of the art technology, using the most advanced switch mode technique available today. RMO600A generates true DC current with automatically regulated test ramps. During the test RMO600A 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 RMO600A instrument can store up to 100 measurements. All measurements are time and date stamped. Using RMOWin software a test can be performed from a PC, and the results can be obtained directly at a PC. Using RMOWin 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 thermal and overcurrent protection. The RMO600A has 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 proprietary hardware and software.

Output current is filtered and has a ripple of less then 1 %. The RMO600A current output is rated at 600 A for 20 seconds, at 300 A for 90 seconds and 200 A for 2,5 minutes at 25 °C ambient temperature.
