Methodology for Metrological Analysis of a Measuring Situation Allowing Consideration of Functional Relationships between Measured Quantities and Examples of its Application

The work is devoted to the metrological analysis of situations of joint measurement of the values of several desired quantities, for which such dependencies between them exist and are known a priori that, for at least one of the quantities to be measured, we can obtain one or more independent estimates with their help from the values of other measured quantities. To calculate the limits of possible error in the results of processing such joint measurements, taking into account the mentioned a priori information, a universal technique is proposed that considers the uncertainties of the results of measurements performed and the parameters of the equations describing known relationships. The methodology is developed for cases when the relationships between measurands are expressed as one or more equations. The paper presents examples of its use for performing metrological analysis of typical measuring situations).
