Забезпечення необхідного рівня надійності й точності засобів вимірювальної техніки регулюванням міжповірочних інтервалів

Based on the analysis of the available verification system of measuring instruments, the inexpediency of a fixed value of inter-verification intervals has been established, and recommendations for the implementation of a different approach to changing the values depending on the operation time have been substantiated. Establishing the patterns of changes in the values of reliability and accuracy indicators over time allows one to increase the metrological reliability of measuring instruments, as well as the operational reliability of radio-electronic devices due to correct assessment of their real technical condition during maintenance and current repairs. The paper for the first time studies the option of reducing the verification intervals of measuring instruments to ensure the required level of their metrological reliability depending on the given value of the complex reliability indicator or the accuracy of measurements of the parameter values of radio-electronic instruments when assessing their technical condition during maintenance or current repairs. The results obtained can be used for versatile determination of verification intervals of both analogue and digital measuring instruments.
