6. Enter the exact ethylene concentration from the calibration standard gas in ppb (ex:
1555 ppb) in the F-900 Controller software.
7. Connect the standard gas to the F-900 intake. Verify that the F-900 measurement
settings have Chamber In, Chamber Out and Closed Loop turned off.
8. Watch the ethylene data on the F-900 Controller software now that the standard gas is
connected. The data should be trending towards the expected concentration and begin
to stabilize.
9.
Wait at least 7 minutes once the signal has stabilized
(and does not change more
than 40 ppb) before setting the span calibration. To set the span calibration, verify the
correct concentration is entered in ppb in the F-
900 Controller software and click the “set
span” button. Note the value below has stabilized at 1.311 ppm.
10. Once the set span button is pressed, the span concentration (ex: 1.555 ppm) should
appear on the F-900 display as well as in the F-900 Controller software. The
concentration level should remain at stable values after setting the span.
