At the National Institute of Metrological Research (INRiM), the first evaluation of an exploratory model in the low-frequency noise in measurements of high-standard resistance commercial bridges and the low limits and high limits has been made using restrictive metrological triangulation rules. The study was performed by observing the ratio measurements of a commercial bridge for the standard resistors in the range from 10 Tohm to 1 Pohm to calculate the type A uncertainty. Keywords: High resistance measurements, equivalent ratio model, measurement uncertainty, self-calibration process, measurement noise, ISO 17025 and the risk assessment.
Presso l'Istituto Nazionale di Ricerca Metrologica (INRiM) è stata effettuata una prima valutazione esplorativa di un modello per il rumore a bassa frequenza delle misure con alti valori di resistenza resistori per un ponte commerciale a doppia sorgente e i valori inferiore e superiore per le regole di triangolazione metrologica restrittive. Lo studio è stato condotto osservando le misure di rapporto di resistenze campione nel campo da 10 Tohm a 1 Pohm, per il calcolo dell’incertezza tipo A. Keywords: Misure di resistori campioni di alto valore, modello equivalente di rapporto di resistenze, incertezza di misura, test di compatibilità, misure affette da rumore, ISO 17025 e la valutazione del rischio.

Abstract
At the National Institute of Metrological Research (INRiM), the first evaluation of an exploratory model in the low-frequency noise in measurements of high-standard resistance commercial bridges and the low limits and high limits has been made using restrictive metrological triangulation rules. The study was performed by observing the ratio measurements of a commercial bridge for the standard resistors in the range from 10 Tohm to 1 Pohm to calculate the type A uncertainty. Keywords: High resistance measurements, equivalent ratio model, measurement uncertainty, self-calibration process, measurement noise, ISO 17025 and the risk assessment.File | Dimensione | Formato | |
