The results of an investigation of the characteristics of transportable voltage standards based on stabilitrons for the purpose
of using them as standards of comparison when transferring the dimension of the unit of constant voltage in accordance with
the State Standard GOST 8.027-2001 are presented. It is shown that, using the standard investigated, one can transfer the
dimensions of the unit of voltage with an overall relative error of 5·10−8 for a voltage of both 1.018 V and 10 V.

The particular features of the synthesis of an alternating current based on the Josephson effect are considered, and diagrams of the phase locking zones are presented which enable the operation of quantum digital voltage synthesizers to be clearly explained. Specific methods for constructing them are described and the requirements imposed on the bias source of Josephson integrated circuits are formulated.Translated from Izmeritelnaya Tekhnika, No. 1, pp. 55–62, January, 2005. 相似文献

This document describes the procedures used at NIST to calibrate dc voltage standards in terms of the NIST volt. Three calibration services are offered by the Electricity Division: Regular Calibration Service (RCS) of client standard cells at NIST; the Volt Transfer Program (VTP) a process to determine the difference between the NIST volt and the volt as maintained by a group of standard cells in a client laboratory; and the calibration of client solid-state dc voltage standards at NIST. The operational procedures used to compare these voltage standards to NIST voltage standards and to maintain the NIST volt via the ac Josephson effect are discussed. 相似文献

Thermocouples with electrodes of pure metals - platinum, gold, and palladium, which are superior in accuracy and stability to standard platinum-rhodium alloy thermocouples, are considered. It is shown that a gold–platinum thermocouple may be an alternative to a high-temperature platinum resistance thermometer.Translated from Izmeritelnaya Tekhnika, No. 9, pp. 46–49, September, 2004. 相似文献
