摘要:
A comparison of the 10 V Josephson array voltage standard of the Bureau International des Poids et Mesures (BIPM) was made with that of the Czech Metrology Institute (CMI), Czech Republic, in February 2011. For this exercise, option B of the comparison protocol was applied for the nominal voltage of 10 V. The BIPM provided a reference voltage for measurement by the CMI using its Josephson standard with its own measuring device (option B of the comparison protocol). The final results are in good agreement within the combined relative standard uncertainty of 10.3 parts in 1010 for the nominal voltage of 10 V.
