Abstract :
A step down procedure is described for establishing voltage standards in the 1 mV to 100 mV range at frequencies between 10 Hz and 1 MHz. The step down employs low voltage thermal voltage converters and micropotentiometers. Techniques are given for measuring input impedance and calculating loading errors.
