- Abstract:
- The National measuring standards ensure the quality of measurements in different areas of science and technology. The actual errors of standards are not the only necessary characteristics to be determined. The long-term stability of the corrections also should be evaluated to guarantee the uncertainty of measurement is within the specified margin and, as a consequence, the metrological traceability is established. This paper mainly concerns the stability evaluation of the top-level standard for metrology service in low-frequency voltage measurement. The AC-DC transfer difference of high-precision voltage converter has been determined for almost 20 years. The measurements performed gave an opportunity to compare the deviations detected with the relevant combined uncertainties. The long-term stability estimate was within 20 μV/V for the frequency of 1 MHz.
