14. Verify that the set air flow values correspond to the flow
measurements:
NOTE:
When using the Certifier FA Plus the air delivery/flow accuracy test
requires that the temperatures of the delivered gas and ambient air must
be within 10
o
C of each other, and that the relative humidity of the gas
must be less than 30% at 21.1
o
C.
Most air flow analyzer flow sensors are sensitive to relative humidity, and
typically indicate higher-than-actual air flow readings when the relative
humidity is above 10%. Consult the manufacturer’s instructions for
correcting any air flow inaccuracies due to high relative humidity.
15. Remove the low-pressure plug and verify that the flow reading on the
analyzer drops by more than 15 SLPM.
