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
o
be within 10
must be less than 30% at 21.1
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.
Set Flow to:
10 SLPM
120 SLPM
230 SLPM
15. Remove the low-pressure plug and verify that the flow reading on the
analyzer drops by more than 15 SLPM.
16. Touch Pressure then Accept to zero the flow setting.
17. The air delivery/flow accuracy test is complete.
