Analysis of frequency characteristics of correction of additive displacements in DC voltage calibrators

It is known that in order to ensure the metrological reliability of measurement industrial means, operative control of their metrological parameters in operating conditions and in real time is necessary to ensure metrological measurement. For this purpose, it is expedient to use portable, many-bit coded-controlled measures of electrical quantities, in particular DC voltage calibrators. Recently, the method of inverting switching is used to correct the error additive component in the measuring instruments.
