RMO-A series of Micro Ohmmeters (hereafter referred to as “RMO-A”) contain 6 models: RMO100A, RMO200A, RMO300A, RMO400A, RMO500A and RMO600A.
All RMO-A models are based on a state of the art technology, using the most advanced switch mode technique available today. The main difference between these models is the maximum test current that can be generated (100 A for RMO100A, 200 A for RMO200A, up to 600 A for RMO600A model).
RMO-A generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO-A ramps with increasing current before measuring and decreasing current after the measurement. This significantly decreases magnetic transients.
The RMO-A instrument can store internally up to 500 measurements. All measurements are time and date stamped. Using the DV-Win soft-ware a test can be performed from a user’s PC, and the results can be obtained directly on the PC.
Communication between the RMO-A and a PC is through an USB (as standard) or an RS232 cable (as an option). Bluetooth communication interface is also available as an option.
Using the DV-Win the result can be arranged as an Excel spread-sheet 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 RMO-A has a very high ability to cancel electrostatic and electro-magnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing a proprietary hardware and software.
The RMO-A instrument has three separate test modes:
- SINGLE mode
- CONTIN mode
- DTRtest mode
