The RMO200D Micro Ohmmeter is designed for contact resistance measurement of non-inductive test objects. RMO instruments are based on state of the art technology, using the most advanced switch mode technique available today.

The RMO200D instrument generates a filtered (ripple free) DC current and output it in an automatically regulated current ramp. The new feature in our Micro Ohmmeter RMO-D series is the ability to perform fully automatic demagnetization of a current transformer core after the measurement.

DV-Win software is included in the device’s purchase price. It enables unit operation from a PC with detailed analysis of test results and test report creation.

DV Win

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 filters.

For the RMO form of DV-Win software there is Help menu available, with detailed instructions and explanations of all functions and features.
