Abstract

Functions for calibration of weights in compliance with international standards are implemented in the current series of Sartorius manual mass comparators. Their intuitive software leads the user step by step through the entire mass comparison procedure. As a result, a record is generated, which contains the relevant data, including measurement uncertainty analysis. The present article discusses the determination of the uncertainty components and a possible method for budgeting these components in order to verify the suitability of mass comparators for various accuracy classes.
