At the National Institute of Metrological Research (INRiM) a first evaluation for systematic errors of a commercial dual source high resistance bridge has been made using restrictive metrological triangulation rules. This technical report exploits the use of the Allan variance and the spectral power density to achieve optimum performances and its limits in case of the high resistance measurement modified Wheatstone bridge of commercial type.

Abstract

At the National Institute of Metrological Research (INRiM) a first evaluation for systematic errors of a commercial dual source high resistance bridge has been made using restrictive metrological triangulation rules. This technical report exploits the use of the Allan variance and the spectral power density to achieve optimum performances and its limits in case of the high resistance measurement modified Wheatstone bridge of commercial type. The study was performed observing the ratios measurements of the bridge for the standard resistors in the range from 10 Tohm to 1 Pohm.
