Four-Wire Measurement: Precision in Electrical Resistance Measurement
Four-wire measurement is a proven method for highly precise electrical resistance measurement. It is an essential technique in electronics manufacturing that ensures maximum precision—and with it, the signature FIXTEST quality.
By deliberately separating current and voltage paths, this method eliminates interfering factors such as contact or lead resistance, enabling reliable results even with the smallest resistance values.
Fundamentals of Four-Wire Measurement
The four-wire measurement, also known as Kelvin measurement, differs fundamentally from the conventional two-wire method. While the latter is affected by the inherent resistance of the measuring leads, the four-wire technique uses separate paths for current and voltage, effectively eliminating this influence.
This enables the accurate determination of even the smallest resistance values.
