The aim of a measurement instrument (MI) calibration is providing metrological traceability of measurement results to SI units through a calibration hierarchy. In the International vocabulary of metrology VIM, calibration is defined as a two-step procedure, which, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. The second stage mostly relates to the use of calibration results and relates to the specific application of MI. Accordingly, when performing calibration, calibration laboratories should calculate uncertainty associated with the defined calibration characteristic. Also laboratories applying calibrated MI have questions relating to usage of the information obtained during calibration to improve the accuracy of their measurements. This article addresses the second problem in the case when the systematic error is estimated in calibration (as deviation of the calibrated MI indications from the reference values specified by the measurement standard). Different algorithms for calculated instrumental measurement uncertainties are analysed and compared.
