Abstract
Considered options for automating the calibration. An automatic calibration system has been developed, investigated and introduced into the production process, which is a software and hardware complex consisting of measuring instruments from the composition of the National standard of voltage unit – volt and additional modules. The automatic system was created on the basis of the modern programming language “Python” with the involvement of the experience of metrologists. A study of the results of calibration of reference voltage measures was carried out: the obtained results of the calibration of the DC voltage (assigned real value with expanded uncertainty) were analyzed in automatic and manual modes and using the “supraVOLTcontrol” system, which implements the Josephson effect. The automatic system was used in the study of the integral instability (nonlinearity) of a digital voltmeter, while a signifi cant minimization of labor costs was obtained. The developed automatic calibration system allows to reduce labor intensity and duration of measurements, provides fl exibility and ability to rebuild depending on emerging issues during research.
