Abstract

The paper presents the instrument and the technique for adjusting and calibrating the inductive voltage divider. The technique is based on comparing two AC voltages of identical frequency. The instrument distinctive feature is extracting and measuring of small differentialmode signal of the voltages being compared within nanovolt and microvolt range against the background of large common-mode signal. The instrument features, its technical and metrological parameters are also considered.
