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.

Improve Productivity by Increasing the Number of Inspection Channels

Combined with the SW1001/SW1002 switch mainframes, the number of measurement channels can be increased up to 132 channels, enabling scan measurements.
