Note: A
zero and normal calibration must be performed on the flow sensor before the
reading is accurate. See Section 6.3 for the calibration procedure.
Note:
To prevent false fault status indications during the change over of gases during
measurement calibration or validation (not flow calibration) the status level of each
flow alarm level will be demoted. A Fault status will be reported as a Maintenance
Requir
ed and a maintenance required status will not be reported at all.
