Description
The authors describe a new Josephson array system which maintains the U.S. Legal Volt. This system is almost fully automated, operates with a typical precision of 0.009 μV, and readily allows U.S. Legal Volt measurements weekly, or more frequently if desired. This system was compared to the previous volt maintenance system, and agreement was made to within 0.03 ppm. This verification is limited by uncertainties in the resistive divider instruments of the previous system
