The Sample Flow screen (read only) displays the current sample flow rate.
The flows is measured by an internal flow sensor.
In the Main Menu, choose Diagnostics > Flow.

The Lamp Intensity screen (read only) displays the current lamp intensity
in Hertz. Normally the intensity would read 90%, but this number will
decrease over time as the lamp degrades.
In the Main Menu, choose Diagnostics > Lamp Intensity.
LAMP INTENSITY:
RANGE
The Optical Span Test screen is used to turn the optical span test LED on
or off, and displays the SO2 concentration reading. Within the
fluorescence chamber is a light emitting diode (LED) which may be used to
simulate a particular concentration of SO
and easy way of checking the optics and electronics for span drift or other
problems.
In the Main Menu, choose Diagnostics > Optical Span Test.
