Background. When solving problems of technical diagnostics, experimental information is used, which is obtained with one or another accuracy, determined by the measuring equipment. To assess the technical condition of the controlled object, it is necessary, based on the measurement results, to identify those structural parameters of the object that are defined as its diagnostic features. Materials and methods. The values of these parameters will be found with some uncertainty associated with the accuracy of the results of direct measurements. The article discusses the dependence of the reliability of the results of technical diagnostics on the accuracy of the results of direct measurements. The used diagnostic equation represents a sequence of elementary diagnostic transformations. Results and conclusions. The initial relations for estimating the probability of correct diagnosis and the probabilities of errors of the first and second kind are given.
