Kelvin clamps are used for optimal contact in four-wire technology. Four-wire measurement is essentialmeasurement even the smallest resistances in the uΩ andspace .

The four-wire measurement has the advantage that the resistance of the measurement lead the contact resistance of the terminal point are eliminated. This requires two measuring leads per terminal point. Since the resistance measurement is taken between two connections—i.e., between two terminal points—a total of four measuring leads are required. Hence the term "four-wire measurement."

The special design of our Kelvin clamps (four-wire clamps) ensures high contact reliability, secure clamping, and low wear in harsh testing conditions.
