Talking about very basic thing: People say the Fluke DMMs are very accurate for measurement. I used few cheap DMMs and and they show different voltages for same supply like 5.01V, 4.98V, 4.99V etc.
Maybe the exact reference of time is the rotation of earth. Same way what is the exact reference of voltage (etc) measurement so people say the fluke or etc expensive tools are very accurate?
How I can compare the accuracy of my poor DMMs?
