One disadvantage of a four-,wire, system is that, obviously, it requires one more ,wire, than a three-,wire, bridge. However, this is a small price to pay given the increased accuracy of the temperature ,measurement, it provides. ,Resistance, to Temperature Conversion. The RTD is a more linear device than the thermocouple, but it still requires

Kelvin (4-wire) resistance measurement : DC METERING CIRCUITS

Kelvin (4-wire) resistance measurement, Suppose we wished to measure the ,resistance, of some component located a significant distance away from our ohmmeter. Such a scenario would be problematic, because an ohmmeter measures all ,resistance, in the circuit loop, which includes the ,resistance, of the wires (R ,wire, ) connecting the ohmmeter to the component being measured (R …

For example, if your current is 1ma, and ,4,.8R -> 5mv. With a 5v Vref to a 10bit adc, that works, barely. Typically the last 2-3 LSB of an adc are fairly noisy. So in that case, you want the resolution to be 15mv (= 3 * 5mv) on a ,4,.8ohm ,resistance,. that least to a minimum current of 15v/,4,.8R = 3mv.
