This article introduces through legal measurement institutions that the FLUKE 732B voltage value as a transfer standard to realized evaluation of uncertainty in measurement for the voltage of DC voltage standard group YCSD-10. A kind of High precision digital meter and scanner with low thermal EMF is designed in this paper. The voltage measurement of DC standard voltage realizes by voltage measure principles of substitution method and design, and establishes the relative mathematical model and factors of ana-lyses of uncertainty in performance testing process. Finally, figures out the dc voltage value standard set of calibration and measure-ment uncertainty.
