Simplifying the calibration of digital voltmeters

Calibration is, undoubtedly, one of the biggest headaches for the user of accurate digital voltmeters. As the measurement capability of digital voltmeters has increased over the last decade, a corresponding increase in the complexity of the calibration sequence has resulted. New technology has now permitted manual calibration to be replaced by a simple, unskilled, procedure taking a fraction of the time previously required. The calibration system described also has a remote, fully automatic, capability
