APPLICATION OF THE METHODOLOGY OF GROUP EVALUATION IN CONTROL OF METROLOGICAL CHARACTERISTICS OF VIBROACOUSTIC CHANNELS OF MEASURING COMPLEXES AND SYSTEMS

Abstract

Background. The relevance of the topic of the work is due to the need to control the metrological characteristics of measuring instruments during their operation. Materials and methods. The use of a group of measuring instruments as a means of monitoring metrological measuring instruments by applying their group assessment without using standards for the timely identification and replacement of measuring instruments with metrological failure is considered. Results and conclusions. The method proposed in the work is based on monitoring and accounting for the drift (drift) of the errors of the measuring instruments during the interval between verification and the assessment of the metrological margin (reserve of metrological reliability) and the analysis of statistical data on the drift of the error during the period of operation of the measuring instruments.
