Pressure
Pressure compensation provides compensation for any changes to the
instrument's output signal due to reaction chamber pressure variations. The
effects of reaction chamber pressure changes on the analyzer's subsystems
and output have been empirically determined. This empirical data is used
to compensate for any change in reaction chamber pressure.
When pressure compensation is on, the first line of the display represents
the current pressure in the reaction chamber. When pressure compensation
is off, the first line of the display shows the factory standard pressure of 300
mmHg.

The Screen Contrast screen is used to change the contrast of the display.
Intensities between 0 and 100% in increments of 10 are available.
Changing the screen contrast may be necessary if the instrument is
operated at extreme temperatures.
In the Main Menu, choose Instrument Controls > Screen Contrast.
