Abstract

High precision voltage calibrations are now regularly performed in industrial calibration laboratories with Josephson array voltage standard systems. A full uncertainty characterization cannot guarantee that the lowest possible uncertainty has been achieved, although uncertainties of less than 10 parts in 10⁹ have been quoted. Comparing systems by reference standard interchange can give greater assurance of low uncertainty capabilities, but additional uncertainty components must also be considered. With a realistic uncertainty statement as a desired goal, uncertainty characterizations of the NIST voltage standard systems along with analysis of Zener reference interchange data will be discussed.
