Precision resistance measurement technology is a method of calculating resistance values by measuring voltage and current in a circuit. By adding a known voltage or current source to the circuit and measuring the voltage and current in the circuit, the resistance value can be calculated according to Ohm's law. Usually, precision resistance measurement technology requires the use of high-precision measuring instruments and equipment to ensure the accuracy and reliability of measurement results

2、 The method of precision resistance measurement technology

There are two main methods for precision resistance measurement: four wire method and six wire method. The four wire method is a commonly used resistance measurement method, which achieves independent measurement of voltage and current by adding two sets of power sources and two sets of probes in the circuit, thereby reducing measurement errors. The six wire method is an improved method of the four wire method, which adds two sets of probes on the basis of the four wire method, further improving the accuracy and stability of measurement. The selection of an appropriate resistance measurement method depends on the actual measurement requirements and environmental conditions
