Процедура оценивания неопределенности измерений при калибровке магазина сопротивления

Abstract

Using the example of resistance calibration on a direct current, the features of taking into account the distribution of input valuess in the procedure for estimating uncertainty when using the method of excesses and propagation of expanded uncertainty are shown. The procedure for estimating the measurement uncertainty is described, and the uncertainty budget is given. An example of uncertainty estimation of measurements when calibrating a resistance box P33 class 0.2 using a Fluke 8508A digital multimeter is described.
