Appendix C Scan/Calibration Procedure
25. The Application gas liquid density default is "Off". Select "1=Change" to set a
value , or "=Next".
26. For Multi Gas Library Application Only: The Application gas GTWA weight
default is "Off". Select "1=Change" to set a value , or "=Next".
27. For Multi Gas Library Application Only: The instrument returns to the Gas
Summary screen for the second gas. Repeat steps 15-26 for each gas.
28. For Single Gas Library Application Only: The Application wave count
default is 1. Select "=Next".
For Multi Gas Library Application Only: Enter the number of wavelengths to
be analyzed.
29. The Wavelength Summary screen shows the wavelength that the analyzer will
measure at. Select "1=Change".
30. Again select "1=Change".
31. Enter the wavelength recorded in step D-2, and select "Enter=Accept" (this
value MUST be entered!).
32. The Wavelength H
humidity compensation. Select "=Next".
33. For Multi Gas Library Application Only: The instrument returns to the
Wavelength Summary screen for the second wavelength. Repeat steps 29-32
for each wavelength.
34. The Application temperature compensation reference default value is "Off".
Select "=Next".
Note: To support temperature compensation, set this value to reference temperature
instead.
35. The Application pressure compensation reference default value is "Off".
Select "=Next".
Note: To support pressure compensation, set this value to reference pressure instead.
36. The Reference Compensation default is "Off". If the application requires a
reference wavelength, (4.004 is recommended), select "1=Change",
"1=Change", "2=Enabled" and "1=Change". Enter the reference wavelength
and "1=Change" to edit the application measurement drift (typically 2.0%).
"=Next" (see "Reference Compensation" in Chapter 7 for an explanation of
this function). Select "Enter=Accept".
37. The Humidity compensation default is "Off". Select "=Next". Contact
Thermo Fisher Scientific before enabling humidity compensation for humidity
compensation coefficients.
O absorbance should be left at the default value to disable
