UNCERTAINTY EVALUATION FOR INDIRECT MEASUREMENT WITH DIFFERENT TYPES OF MEASURING DEVICES

V. Didenko

Abstract

The paper gives formulae for uncertainty evaluation of indirect measurement based on direct measurements by different types of measuring devices at different ranges as well as nominal values of quantities produced by measures. One type has specifications of total error (multimeters, e.g.), while other type has specifications of offset, gain and linearity errors (data acquisition devices, ADC). Choice of range for devices with specifications of separate errors is considered.
