Thermo Fisher Scientific
The Intensity Check menu is used to manually control the flow of
reference of sample gas through the photometer. This enables the intensity
and noise reading of the detector to be determined with either reference or
sample gas flow. Selecting any of these menu choices will disturb the analog
outputs. The intensity check is visible only if the photometer option is
installed and when the calibrator is in service mode. For more information
on the service mode, see
In the Main Menu, choose Service > Intensity Check.
