DC Voltage Linearity Measurements and DVM Calibration with Conventional and Programmable Josephson Voltage Standards

Regis Pinheiro Landim, Waldemar Guilherme Kürten Ihlenfeld
Abstract:
Traditional calibration of dc voltage high accuracy digital voltmeters (DVMs) using conventional and Programmable Josephson Voltage Standards at INMETRO show improvements between 73.7 % and 98.3 % when compared with a regular calibration technique. Some calibration results as well as DVM linearity and gain drift analysis (up to 10 V range) are presented and discussed in this paper.
