WebJun 15, 2024 · Because each white wire has the same resistance (theoretically) as the resistance across the red wire, the voltage drop across the RTD is: V RTD = V A - V B As the temperature changes, the lead resistance will also change, but when using the three-wire system, the resistance change will be predictable. WebMar 17, 2024 · Step 2: Check the White Wire First. Use the multimeter to check the 3-wire RTD. Refer to the MFG for the wiring and color code. Here (see the picture below), it has been connected first to the white wire and the other probe to another wire. Take note of the reading, which is close to 110 ohms.

WebNov 15, 2016 · Each side of the RTD has two wires attached. Each wire is maybe 1 Ω of resistance. When connected to the amplifier, the smart amp will measure the voltage across the RTD and also across the wire pairs. For example, here's the approximate resistances of a 4-Wire PT100 RTD at 0 ° C (for a PT1000, the middle resistance would be (1002 Ω rather ... fish finder movement
