The contact resistance is the impedance to the current through the closed contact pair. This type of measurement is performed on devices such as connectors, relays, and switches. This resistance is usually very small, ranging from microohms to a few milliohms, so a 4-wire measurement is required. Programmable scanners dramatically reduce measurement time by switching a set of test instruments to multiple contacts. For example when testing multiple pin connectors or automatically testing multiple contacts in an environmental chamber.
