Popis: 1. From the study, an interrelationship has been found between the technical characteristics of testing instruments for nonelectrical quantities and the set of characteristics and qualities of both the PT and the interfering activities. As a result, a quantitative expression has been obtained in a general form that applied with equal validity to different types of testing instruments for nonelectrical quantities. 2. The ratio of the reliability margin to the power of the random interfering activities serves as a generalized measure for the capacity of the instrument's technical and operational characteristics. 3. The boundedness of the reliability margin for one or another type of PT at a certain level of their development permits an estimate to be made of the possibility of creating instruments with prescribed characteristics for specified operating conditions. 4. The limiting value of the invariant factors that evaluate the information potentialities of instruments for nonelectrical quantities using natural types of modulation is determined by a quantity that is inversely proportional to the square root of the PT's “dead time”.
