Reducing Resistance Measurement Uncertainty: DC Current Reversals vs. Classic Offset Compensation


Device manufacturing, quality assurance, and research groups often make resistance measurements (force current/measure voltage) to monitor, evaluate, or study the quality of their devices and materials. These device manufacturers could be relay, connector, or MR head suppliers. While the device manufacturer would likely employ contact resistance measurements, under dry circuit test conditions, for a life cycle test, a quality assurance test group would measure resistance to evaluate an automotive connector in a salt environment test. Similarly, a materials researcher might measure resistance to study metal lattice structures under very high compression forces. White Paper #2040
