4 Terminal sensing (a.k.a. 4-wire measurement) also called Kelvin Measurement or Kelvin Techniques: measurement of resistance, especially for very low ohms. Here we listed 3 methods about Kelvin Measurement.
FORT's metal alloy current sensing resistors fit for 4 points measurement method (a) for better reliability.
Indication:
1 and 4 current
2 and 3 measuring
