38. The Application pathlength can be set for "Long" or "Short". Press
"1=Change" to select the appropriate pathlength and then "

=Next". For
optimum sensitivity the long pathlength should be used. The short pathlength
is recommended for very high concentration measurements.
39. The Application dwell time default is "275". Select "

=Next".
40. The Application purge % of max default is "100%". Select "

=Next".
41. The Application batch mode default is "Enabled". Select "

=Next".
42. The Application batch purge % default is "100%". Select "

=Next".
43. For Single Gas Library Application: From the Meas Absorb

Conc screen,
enter the measurement absorbance concentration. These values MUST BE
ENTERED. Select each parameter and "1=Change".
For Multi Gas Library Application: From the “Matrix Parameters” screen,
select “1=Change”.
44. For Single Gas Library Application Only: In the PQ Cal Range screen, select
"1=Range".
45. For Both Single and Multi-gas Library Application: Select "1=Q" and, since
the quadratic term is unknown at this point because the P-matrix has not been
generated yet, enter “0” and then “Enter=Accept”.
46. For Both Single and Multi-gas Library Application: Select "2=P" and, since
the linear term is unknown at this point because the P-matrix has not been
generated yet, enter “1” and then “Enter=Accept”. Note that for multi gas
library applications, steps 43 and 44 must be repeated for each gas at each
wavelength.
47. For Single Gas Library Application: From the “PQ cal params” screen, select
"4=Absorb range" and enter "1.2". Select “Enter=Accept”.
48. For Both Single and Multi-gas Library Application: Press "ESC" until
analyzer asks to save changes. Select “Enter=Save”.
49. For Both Single and Multi-gas Library Application: Press "ESC" 2 times to
return to the main menu. At this point the application is valid for use.
