Abstract

A portable Josephson voltage standard (JVS) system has been used as a transfer standard to make an interlaboratory JVS comparison. The results are compared with an interlaboratory comparison between the same two JVS systems using transport Zeners made at about the same time. The portable JVS improves the uncertainty of the comparison between the two JVS systems by a factor of 13 compared to the uncertainty using a conventional Zener MAP procedure. This is largely due to the elimination of the problems associated with non-ideal Zener transportability, environmental dependance, and non-linear drift.
