The RMO-H series – battery operated and handheld micro-ohmmeters are unique solution for the contact resistance measurement of switchgears according to international standards (e.g. IEC 62271-100). RMO-H can be used for number of applications where non-inductive resistance is checked, during factory inspections or testing in the high-induction field environments. The set is equipped with the overcurrent protection.

Typical application is accurate low resistance measurement during manufacturing, commissioning and
maintenance inspections on:
 High and medium voltage Switchgears and Circuit Breakers (as per IEC 62271-100 standards)
 High and medium voltage Disconnecting Switches (as per IEC 62271-100 standards)
 High-current Busbar joints
 Terminals of the conductors on HV power lines
 Bonding of Lighting conductors

RMO-H instruments are also ideal testing tool for quality control checking during production process of
high-voltage equipment and equipment used in railway and aircraft industry:
 Welding joints
 Cable splices and cable resistance
 OLTC contacts checking (off-line, not connected to transformer)
 Railway joints, lines and conductor rails
 Bonds and joints checking in aircraft manufacturing industry
