Abstract :
The configuration and performance of a system based on the Josephson junction array of 1 V, which has been used to maintain a primary voltage standard, are described. Details of the components are given. An uncertainty of 1.8*10/sup -8/ was obtained at least for the calibration of a Zener voltage reference in a run of 45 min.<>
