    Metrological risks and state of the monitored objects
    (Lviv Politechnic Publishing House, 2022) Yatsyshyn Svyatoslav; Baitsar Roman; Lazarenko Serhiy; Lazarenko Nadiia; Mastylo Rostyslav
    The metrological risks of goods production are studied in the work. They are estimated conjugating with the existing technology as well as its metrological support. It is confirmed that in addition to the factors due to the processing of measurement results, the peculiarities of metrological support should be taken into account. One of the characteristic parameters of the metrological instruments is the variance of the measured value. Multiple measurements of the electrical resistance of the mentioned instruments – high-precision resistors designed for indirect measurement of current by measuring the voltage on them, using a DC bridge, were performed. The variance of obtained results is estimated, depending on the number of repeated measurements, the time interval between them, etc.
