| Description | Journal: Metrologia The one volt standards of the Electrotechnical Laboratory (ETL), Tsukuba, Japan, and the Bureau International des Poids et Mesures (BIPM), Sèvres, France, were compared by three methods: direct comparison of the outputs of Josephson junction arrays; indirect comparison via a voltage transfer standard; and simple comparison of standards based on Zener diodes calibrated with the array instruments. The first two methods show no difference between the two array standards to within a type A uncertainty of 1,5 parts in $10^{10}$ (0,15 nV). The combined uncertainty for the first two methods is 0,2 nV. For the Zener diode measurements the ETL value was 2 nV higher than that of the BIPM when the Zener diode device's output was grounded and 16 nV lower when it was floating. |
