Overview


The Winding Ohmmeter RMO50M is a portable and lightweight instrument (8,0 kg / 17.6 lbs) designed for the winding resistance measurement of electrical motors and generators. The RMO50M instrument is based on the state of the art technology, using the most advanced switch mode technology available today. It generates a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current into the test object is automatically regulated. The two independent channels enable testing of two windings in series.
