4.4 Manual Calibration
After preparing for the calibration (see “ 4.2 Preparation for Calibration ” (page 14)), perform
the zero calibration and the span calibration in this order.
4.4.1 Operational flow
The operational flow for manual calibration is described below:
Note
Control the zero gas and span gas feed pressures at atmospheric pressure plus (0 kPa to 0.5 kPa).
