Hioki DC resistance meters measure a broad range of resistance values at a high level of precision. The RM3545 is super-high-precision, multichannel-capable resistance meters that meet applications in advanced research and production for testing winding resistance of motors and transformers; contact resistance of power relays, switches, and connectors; and resistance of signal relays and magnetic parts.

How to Use Resistance Meters: Measuring Contact Resistance with the Low Power Resistance Function

IEC standards define the method by which to measure the contact resistance of connectors and relays used for very low signals. The Hioki RM3545 Resistance Meter meets those standards with its low power resistance function, also known as the dry circuit test. To reduce the effects on any deteriorating contact surface, the open terminal voltage is capped at 20mV, while the maximum measurement current never exceeds 1mA, delivering the ideal testing environment for measuring contact resistance from the 0.1μΩ to 1kΩ range.
