We reviewed the state of the issue of verification of modern digital devices, including modern electricity meters, and various measurement systems.

Modern microprocessor digital measuring devices may well be attributed not to measuring devices, but to measuring and computing complexes, as the comparison showed. In this case, in some cases it would be useful to extend the methods for determining and controlling the errors specified in MI 2440–97 to calibrate and / or calibrate such instruments.

We believe that the listed issues require a good scientific study, regardless of whether or not they are used to verify digital measuring devices as a set of measuring channels of a measuring and computing complex. We have given directions for further research.
