High DC current resistance meter for motors/generators
Description

The Winding Ohmmeter RMO100M is designed for winding resistance measurement of electrical motors and generators. RMO100M generates true DC ripple free current. The test result is displayed as R=U/I. The RMO100M instrument can store up to 500 measurements. All measurements are time and date stamped. Using RMOWin-M software a test can be performed from a PC, and the results can be obtained directly at a PC. Using RMOWin-M the result can be arranged as an Excel spreadsheet which can be later shown as a diagram and printed for a report. The RMO100M has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary hardware and software.
