Abstrakt: Until now digital measuring instruments have rarely matched the result devices with the psychological properties of an operator. Such a situation has been caused by a number of reasons, and particularly the conviction that subjective errors are not characteristic of digital devices and also by the lack of suitable recommendations. Comparative analysis of the information characteristics of digital and analog readouts, conducted in this work, allow us to recommend the following measures for increasing the effectiveness of the perception of the indications of digital indicators: use of information redundancy for the creation of a spatial visual form, corresponding to the equivalent analog readout by addition of one or several dimensionalities; elimination of the noninformational content (noise) from the readout with the aid of an indication register; separating out the dynamics of change of indications.
