RMO-A series of Micro Ohmmeters (hereafter referred to as “RMO-A”) is based on a state of the art technology, using the most advanced switch mode technique available today.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 eliminates magnetic transients.
The RMO-A 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 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.

RMO DV-Win Software provides several advanced features as a supplement to multiple functions of RMO devices. Testing in Continuous mode is upgraded with a sample time feature which allows user to record test results in specific time intervals set in seconds. After performed measurements results can be saved in a various formats and test report can be generated and saved or printed. Result can also be downloaded from the device to the PC by use of several different search filter.
For the RMO form of DV-Win software there is Help menu available, with detailed instructions and explanations of all functions and features.
