  • Abstract
    This paper describes an DC voltage calibration system which is improved to be more accurate and more easy to operate. It is based on 10 V Josephson array, and uses a fully automated system consisting of switches setup well designed for accurate measurement. An overall standard uncertainty is estimated less than 5 nV(1sigma) at 10 V level.
