Hioki DC resistance testers measure a broad range of resistance values at a high level of precision. The RM3548 is a high-precision, portable resistance tester capable of measuring resistance levels from microohms to megaohms, and is intended primarily for use in testing and maintenance of large equipment, for example, measuring the winding and weld resistances in large motors.
