Temperature Measurement Methods There are several techniques for meas- uring temperature with a thermistor, the most common being the two-wire and four- wire techniques. The two-wire technique works by forc- ing current through the thermistor and measuring the resulting voltage. The benefit is that it's a simple method using only two wires, making it easy to connect and imple- ment. The main drawback is that the lead resistance is part of the measurement, which Basics of Temperature can cause some error. In the four-wire technique, a current is forced through the thermistor and a voltage Measurement: is measured. However, the current is sourced
