Abstract
A measuring amplifier () with background calibration and adjustment amplifies, digitizes and processes at least one measurement signal () from at least one measuring transducer () with the aid of at least one amplifier arrangement (). This can be intermittently replaced by an additional amplifier arrangement (), which enables interruption-free direct calibration and, if necessary, adjustment of the amplifier arrangement. In the calibration, both a zero point error and an amplification error of the amplifier arrangement are reliably determined. A high accuracy is achieved without measurement interruption. Only one additional amplifier arrangement is generally required, even for a measuring amplifier with plural channels.
