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.

Presso l'Istituto Nazionale di Ricerca Metrologica (INRiM) è stata effettuata una prima valutazione degli errori sistematici per un ponte commerciale ad alta resistenza a doppia sorgente utilizzando regole di triangolazione metrologica restrittive. Questa relazione tecnica sfrutta l'uso della varianza di Allan e della densità di potenza spettrale per ottenere i limiti di queste regole nel caso del ponte di Wheatstone modificato di tipo commerciale. Lo studio è stato condotto osservando le misure di rapporto di resistenze campione nel campo da 10 Tohm a 1 Pohm.

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.| File | Dimensione | Formato | |
