Reduced resistance of resistor

<< < (8/8)

Yeah, among all the speculations surrounding thermals and resistor properties and lead resistance and 4 wire measurements and European commas and so on, we seem to miss the elephant in the room...

According to mfr specs, a reading of 0.7 ohms can be off by +/- 0.5 ohms with many/most multimeters (my Klein has about the same specs as the Hioki, 1% +/- 5 digits).

 

wraper:
It's not only about multimeter specs but also about lead and contact resistance.

Yes. That statement is sufficiently general and non-specific to be true and relevant in some cases.  :D
