The PUMA method applied to the measures carried out by using a PC-based measurement instrument

Abstract

The paper deals with the uncertainty management in the measurements performed by using a generic PC-based measurement instrument. To accomplish the task, the uncertainty estimation is performed by using the PUMA (Procedure for Uncertainty MAnagement) method, which is an iterative technique completely based on the “Guide to the Expression of Uncertainty in Measurement” rules, but which offers a more engineering methodology. With this approach, it is possible to optimize the cost of the measurements versus the uncertainty target, avoiding the use of inadequate or, on the contrary, too expensive instrumentation. According to the PUMA method, in the paper different approaches to evaluate the uncertainties are presented, starting from the more precise methodologies and keeping on with the coarser, but quicker and cheaper ones.
