The RMO-E instruments are designed and ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1. 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 instrument automatically generates increasing current before measuring and decreasing current after the measurement. Consequently, this significantly decreases magnetic transients and ensures great accuracy.
These 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:
