the analyzer is zeroed and spanned as usual. Then, each special calibration gas, foreachoftheintermediatecalibrationpoints,isflowed,inturn,throughthe sensor.Aseachgasflows,thedifferentialvalueforthatintermediatecalibration point is entered from the front panel of the analyzer.
Note: The span gas used to span the analyzer must be >90% of the range being analyzed.
