that also known as Four-line method testing technology. More
details show in Figure 2.
Figure 2 Schematic diagram
The current goes through I+ and I- ports to the resistance Rx,
current value can be got from the ammeter I, and the voltage
between V+ and V- will be shown in the voltmeter V. Based on data
I and V, the resistance value can be calculated.
From the above diagram we can know that using four-terminal
measurement can eliminate the error caused by lead resistance
and contact resistance.
