Abstract
The problem of calculating the expanded uncertainty of measurements during calibration is examined. Two sources of measurement error are identified: the uncertainty of the reference value obtained from a standard and the dispersion in the readings from the measuring instrument that is being calibrated. A Bayesian approach is used to determine the dependence of the coverage factor on the number of repeated measurements and the relationship of these uncertainties.
