RMO-E Series

The RMO-E instruments are designed and ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1.

Description

RMO-E series instruments are used for the ground grind testing of the electrical equipment.

Also, they can measure the resistance of high, middle and low voltage circuit breakers, high-current bus bar joints, cable splices, and welding joints. The instruments accurately measure not only in factory environments but also in high-induction fields and substations.

Both models generate a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. During a test, the protective bonding testers automatically generate increasing current before measuring and decreasing current after the measurement. Consequently, this significantly decreases magnetic transients and ensures great accuracy.

RMO-E series instruments can store up to 500 measurements in the internal memory and have a built-in thermal printer available as an option.

DV Win software communicates with the RMO-E earth resistance meter via USB or RS232 interface. It allows a user to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.

The RMO-E series contains two models, RMO60E and RMO100E. The main difference between these two models is in the maximal test current:

  • 60 A DC for RMO60E
  • 100 A DC for RMO100E
