Annotations languages:

The question of introduction of the concept of uncertainty of measurements is considered at carrying out of verification of analog electric devices of direct action on an example of analogue voltmeters. Uncertainty of defining of the basic error of the voltmeters which are one of the basic indicators at an estimation of conformity is evaluated.
Keywords: uncertainty of measurement, an error, fitting criterion, extreme error, standard uncertainty, the total standard uncertainty, the expanded uncertainty
