Summary of the subject: The discipline "Verification of measuring equipment" is one of the main mandatory professional disciplines of professional and practical master's training in specialty 152 "Metrology and information and measuring equipment". The purpose of teaching the discipline is for students to study modern methods and means of verification (metrological verification) of measuring equipment (MET), to acquire the ability to conduct a measuring experiment and to process its results in order to establish the conformity of the tested MT to the requirements of regulatory documents (ND) and its suitability for use . The discipline "Verification of measuring equipment" consists of a lecture course, a laboratory workshop, calculation work (for full-time students) and control work (for part-time students). The structure of the course "Verification of measuring equipment" and its teaching methodology are aimed, first of all, at the consideration of issues that are common to the verification of various types of METs intended for the measurement of various types of quantities of both electrical and non-electrical nature, as well as issues related to the calibration of METs: ¦ study and analysis of FTA verification methods, since the same method can be used to verify different types of FTA. For example, by the method of direct comparison of the tested test equipment with the reference one, the verification of direct evaluation measuring devices intended for measuring both electrical quantities - ammeters, voltmeters, wattmeters, etc., and non-electrical quantities - liquid and gas flow meters, manometers, viscometers, etc. .; ¦ study and analysis of measurement methods, since the same method of FTA verification can be implemented by using different measurement methods, which determines the methodology of processing FTA verification results and assessing their accuracy. For example, the method of comparing the FTA under test with the reference one with the help of a comparator can be implemented by using such measurement methods as the substitution method, the contrast method, the differential and zero methods; ¦ assessment of the accuracy of the results of the verification of the FTA and their reliability is carried out according to the method of calculating the uncertainty (uncertainty) of the measurement result in the procedure of verification and calibration of the FTA, which is calibrated, which corresponds to the modern trends in the development of world metrology. The material of the course "Verification of measuring equipment" can be used by students in the process of completing master's qualification works.
