Description: The article presents proposals for the improvement of the verification scheme of high-precision voltmeters with a permissible basic error of measurements ±0.05 % and more. The method of determination by the metrological characteristics of high-precision voltmeters using thermal converter. Developed the scheme of verification, which implements this method. Analysed advantages of the proposed method. Justification of the main statements on the use of the proposed method and schemes will done.
Keywords: thermal converter, scale transformer, sett, scheme
