Abstract

The article concerns a very important problem in metrology – the increase of precision of automatic quadrature bridge for the assessment of inductivity unit. It was carried out the analysis of measurement error for imbalance universal automatic quadrature bridge and estimated impact of the major destabilizing factors in the measurement of the ratio of two impedances, all of these permits to get high accuracy, simple design and low-cost devices.
