Kelvin Measurement
Kelvin Measurement is a measurement method for the precise determination of small electrical resistances and is also known as four-wire measurement.
By separating the current and voltage lines, the effects of line and contact resistances are minimized, resulting in particularly accurate measurement results.
In test engineering, the Kelvin Measurement is used to reliably determine transition resistance of Contact Probes, connections, and contact points.
FAQ
It is used to avoid measurement errors caused by line and Contact resistance and to precisely measure very small resistances.
The test current is supplied via two wires, while the voltage is measured via separate wires, ensuring that voltage drops across the wires do not affect the result.
It enables high measurement accuracy, particularly at low resistances, and provides reproducible measurement results.
