Hello all,
You may have a look at my document on:? Calibration Techniques for the Home Lab
I have had good results with a full wave rectifier using 0.1% resistors, as shown on page 25.
Using a thermocouple will provide even better accuracy, provided you use 6.5 digit DC voltmeters.? Starting at page 30.
That gives me a precise 1.000 VAC reference which allows verification of my multimeters.
A stable AC source driving an amplifier with? Kelvin Divider allows for checking at voltages up to 200VAC.
