4.8.2.3 Auto Mode Linearization
To linearize in the Auto Mode, you must have on hand a separate calibra- tion gas for each of the data points you are going use in your linearization. First, the analyzer is zeroed and spanned as usual. Then, each special calibration gas, for each of the intermediate calibration points, is flowed, in turn, through the sensor. As each gas flows, the differential value for that intermediate calibration point is entered from the front panel of the analyzer.
