KC4: Kelvin Clips (1 Set = 2 pieces) for 4-pole connections of low-resistance test objects, cable length 120 cm, clamp for connections to test objects up to 30 mm Ø. The Kelvin Clips connect low-resistance resistors (e.g., contact resistances, shunts, ...) to a resistance measuring device using four-wire technology. This compensates for the lead resistance. KC4 consists of 1 pair of clamps.
