MICRO OHM METER RMO-H SERIES

The RMO-H is battery operated and handheld micro-ohmmeter. It is designed for a variety of applications for contact resistance measurement of non-inductive test objects. Typical applications are accurate testing of:

• medium and high-voltage circuit breakers,
• disconnecting switches,
• high-current bus bar joints,
• cable splices,
• and different high-current links.

Even more, it accurately measures in high-induction filed environments and substations, as well as in factory testing.

RMO-H Series contains six models in total, divided in 2 sub-series depending on the test leads length requirement and the battery type:

• RMO-H1, RMO-H2 and RMO-H3 models are intended for use with short cables (e.g. 1,3 m / 3 m / 5 m). The 1-cell Li-Po battery with 8200 mAh capacity provides output voltage up to 4,1 V DC.
• RMO-H21, RMO-H22 and RMO-H23 models are ideal for applications where test leads with lengths > 5 m are required.  The high output voltage (up to 8,3 V DC) is provided by 2-cells 4100 mAh Li-Po battery.

The test current is regulated and can be selected in a range of 1 A to maximum 300 A, depending on the maximum test current rating:

• RMO-H1, RMO-H21 models – up to 100 A DC
• RMO-H2, RMO-H22 models – up to 220 A DC
• RMO-H3, RMO-H23 models – up to 300 A DC.
