High DC current winding resistance meters for electrical motors & generators

Winding Ohmmeters RMO-M series are designed for winding resistance measurement of inductive test objects such as electrical motors and generators.
RMO-M instruments are based on state of the art technology, using the most advanced switch mode technique available today. RMO-M generates true DC ripple free current with automatically regulated measurement and discharge circuit.
