【Abstract】 The nonlinearity,temperature drift,time drift,transient or stable state errors in the precision voltage measurement are self calibrated by time series analysis,linear or conic regress prediction,so the precision is only determined by the voltage references and the resolution of the measuring circuits.更多还原
