The name "Kelvin" describes the used 4-wire technology: the test signal and the measurement signal (sensor line) are transmitted separately to the DUT. Low impedance measurements are possible only with this technique. The Kelvin terminals are used if connections such as threaded bolts or free cable ends must be contacted.
The Kelvin terminals are also used in ground bond tests: Low impedance cables are measured here with the ground bond tester. The Kelvin terminals of SPS electronic are of high quality and available in different versions. The exchangeable clamping jaws allow connection of free cable ends as well as threaded bolts.
