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).
