Abstract

The calibration of a pressure balance involves taking measurements of pressure, applied load and temperature, and estimating from these the values of parameters that define the effective area of the balance as a function of pressure. In this report we discuss and assess various approaches to analysing the measured data to obtain these estimates. In practice, the so-called - and -methods are used for the analysis, and we indicate properties of these methods viewed as linear estimators of the effective area parameters. The stated properties are verified by applying the methods considered to a variety of simulated data sets. Furthermore, the numerical simulations provide a means for quantifying and comparing the performance of the methods.
