ABSTRACT:
A method and apparatus for correction of null or zero reference offset error occurring in a measuring or transducing device by reason of temperature change, component ageing or other effects. A system including an appropriately programmed microcomputer, an analog-to-digital converter, a digital-to-analog converter and an operational amplifier provides a closed feedback correction loop, controlled by the microcomputer, which can maintain the zero adjustment of an analog transducer and amplifier circuitry over an indefinite period of time.
