Dipole high current probes (Kelvin probes) are used to perform four-wire measurements directly on the contact surface. In doing so, the voltage on the inner conductor and the current on the outer conductor are measured. This enables precise resistance measurement on accumulators or flat connector blades (the resistance of the measurement cable is not part of the measurement).

Dipole high current probes either have a coaxial design with central inner conductor, or are four-wire clamps with galvanic insulted spring clips. 

The high current clamp series HKR and HKF enable secure, scratch free contacting of round posts and flat connector blades using contact lamellae. The lamellae close only once the unit under test has reached the base of the high current clamp. The high current clamp for round contacts are especially recommended for round contacts which cannot be contacted on their top side due to protection covers. In challenging test conditions with vibrations and longer test cycles, high current clamps are ideally suited thanks to their robust design.

Robust high current test probes stand out due to their sturdy design and are ideally suited for challenging atmospheric conditions with side forces and vibrations present. They are also suitable as a permanently assembled element in machinery. In combination with available contact terminals, interface blocks or transmission contacts can be created.
