Uncertainty Budgeting for Range Calibration



Ruediger Kessel, Raghu N. Kacker, Klaus-Dieter Sommer


The Guide to the Expression of Uncertainty (GUM) in Measurement established a general procedure to evaluate measurement uncertainty. The Guide covers only the evaluation of a single result or a set of results. Modern measurement instruments and procedures operate over a wide range of values. Therefore in practice a calibration procedure is needed that is valid for this range. It should include an evaluation of uncertainty associated with the calibration results and for the subsequent measurements performed with the calibrated instrument. Traditionally regression is used for this purpose. In this talk we will discuss the weaknesses of the regression approach and suggest an alternative to overcome the weaknesses.
