what is a 4-wire resistance measurement? - NI Community

4,-,wire resistance, measurements are used when you need either very-high accuracy, or the ,measurement, leads are very long. The way a normal 2-,wire resistance measurement, works is that a fixed current is passed through the ,resistance, being measured and the meter reads the voltage drop across the unknown ,resistance,, and Ohm's law allows the meter to calculate the ,resistance,.

Resistance measurement; 2 3 or 4 wire connection – How ...

4-,wire resistance measurement,. With the 4-,wire, connection, the idea is to have separate wires to deliver the ,measurement, current and to measure the voltage drop over the ,resistance,. For this kind of connection, 4 wires are needed, leading to the name. Pretty logical… Let’s look at a picture to illustrate a 4-,wire, connection:

Figure ,4,. A ,4,-,wire measurement,. Notice the meter has four connections. Figure 5. A ,4,-,wire measurement, gives you control of where the voltmeter connects. The disadvantage of ,4,-,wire, testing is it takes four connections to do the test, but it does give you an accurate ,resistance measurement, of the DUT without the ,resistance, of the test leads.

4-wire Kelvin 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 …
