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.
When measuring low resistance, due to the voltage generated when different metals come into contact with one another (known as electromagnetic force, or EMF), the measurement values can be unstable. The Hioki RM3545 is built in with an Offset Voltage Compensation (OVC) function to correct for the effects of EMF, making the instrument ideal for measuring low resistance of the welding points of busbars.
Verify the quality of the battery by seeing the resistance of battery tab welding and busbars.
Discover energy loss to improve your batteries.
The RM3545 allows you to identify defective welding that causes increased resistance at junctions, causing greater heat/energy loss during charging and recharging.

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