Air Pressure Effect
Which analyzer
modules have a
pressure sensor?
Air Pressure Values
9-28
A specific amount of change in air pressure will result in a specific change in a
measurement value, depending on the measurement principle employed by the
analyzer module.
Air pressure effect can be minimized by:
• Installing a pressure sensor in the analyzer module (this can only be done at the
factory) or
• Entering the current atmospheric pressure as a correction value.
