![]() Consequently the measurement of DUT resistance is more accurate.Ī 4-wire resistance measurement uses a Kelvin bridge or Wheatstone bridge to eliminate the lead resistance in the measurement device.Įlectrom’s iTIG III series of motor testers and winding analyzers use highly accurate 4-wire winding resistance measurements. In other words, only the DUT resistance is measured, the resistance in the leads from the measurement device to the DUT is eliminated. Each pair has a drive lead and a sense lead, and the resistance is “sensed” or measured from one Kelvin clamp to the other. With a 4-wire measurement 4 leads come from the measurement device and are connected in pairs to the ends of the DUT using what is called Kelvin clamps. Our 4-wire resistance measurement uses Kelvin clamps for improved accuracy ![]()
