So I have an resistance temperature detector (RTD) that when I measure the resistance, it's 100 Ohms, then when I switch the leads around and measure, it reads 95 Ohms. This is not a cheap part, it's being used by the Airforce, so why does the resistance differ when I just switch the leads around?
This also happened on this precision potentiometer I bought. It's 200 Ohms and 3%. I set it to 100 ohms and measured. Then switched the leads around and measurements went off by 4 Ohms.
These two things are basically resistors right? Why would just switching the leads around give a different reading?
