Abstract

Systematic error of digital measurement system (DSM) mainly exists in the analog measurement channels. The cause of systematic errors is circuit status and parameters of OPA, DAC and reference circuit which drift with changes in temperature and time deviate from the standard values. In this paper, firstly the causes of DMS errors are analyzed and errors calibration formula based on the one element linear regression is derived. Secondly equivalent formulas of zero drift, multiplying power changes and cascade in analog measurement channels are derived. Finally calibration of analog measurement channels is implemented in an engineering example.
