Abstract
Many electrical standard laboratories use μpots as the primary standards for low ac voltage measurement. To determine the ac-dc difference of a μpot usually requires a transfer standard which has high input impedance for the standard values transferred from a standard μpot through a step-down procedure. In order to lower the uncertainty of the μpot ac-dc difference measurement, after several step-down procedures at low voltage range, a precision comparison method is introduced
