Annotations languages:

The reference standard of variable voltage a wide frequency range of 10 Hz to 1 MHz is created in Estonia on the basis of ac/dc thermal transfer standard Fluke 792A. At first stage requires application of a new method of an estimation of uncertainty at model of measurement with application of the standard in a case of varying accuracy and correlated measuring results to experiment.
