RMO-H series contain two models: RMO-H2 (test current up to 220 A DC), RMO-H3 (test current up to 300 A DC)
RMO-H is a handheld, battery operated Micro Ohmmeter based on a state of the art technology, using the most advanced battery and switch mode technique available today.
The high-capacity Li-Po battery enables generating a true DC ripple-free current up to 300 A. The test current is user selectable and generated in an automatic regulated test ramp.
During a test the RMO-H ramps with increasing current before measuring and decreasing current after the measurement. This significantly decreases magnetic transients.
The RMO-H instrument can store internally up to 1000 measurements. The results are saved on the micro SD card. All measurements are time and date stamped.
DV-Win software enables download of the results, creating and exporting test reports in different formats. Communication between the RMO-H and a PC is through a Bluetooth connection.
The set is equipped with the thermal and overcurrent protection.
Typical application is measuring a resistance of non-inductive test objects:
High, middle and low voltage circuit breakers
High and middle voltage disconnecting switches
High-current bus bar joints
DV-Win software (*included in the purchase price): DV-Win Software for the RMO-H device is an application set of tools based on the Windows operating system. It enables the two-way communication between the RMO-H device and a standard PC over the Bluetooth connection. The main features of the software are:
Download of the test results to a PC
Analysis of the test results
Saving the test results in different formats
