What is "OVC" on the RM3545?

QWhat is the OVC function of the RM3545?


"OVC" represents "Offset Voltage Compensation".

Low resistance measurement may be affected by the thermal electromotive force generated at the contact of different metallic materials probe contact).
OVC function compensates the effect of this thermal electromotive force in order for the Resistance Meter RM3545 to measure low resistance accurately.

This is useful for measuring the contact resistance of connectors or relays,welding resistance of busbars, etc.
