An interlaboratory comparison at 10 V dc has been made among 16 national, industrial, and military standards laboratories in North America. The comparison used a set of four traveling Zener dc reference standards. A pivot laboratory made measurements at the beginning, at the end, and at four other times during the comparison. The measured differences and(More)
The 10 V Josephson voltage standard (JVS) systems of the National Institute of Standards and Technology (NIST) and the Sandia National Laboratories (SNL) were compared by two different methods used simultaneously. The first method uses the well-established technique of the NIST’s Measurement Assurance Program (MAP) in which Zener-diode electronic voltage(More)
