Abstract :
The paper describes a modification of a step-down calibration procedure for determining ac-dc transfer difference of an electronic low voltage transfer standard. The described procedure, utilizing an additional standard does not require corrections of the loading error. The paper shows that the input impedance of the standard changes from unit to unit and that each unit requires individual characterization, to be used to calibrate low voltage ac calibrators
