8.1 Pressure Correction
To eliminate faulty measurements due to changes in barometric pressure or sample gas
pressure, the operator is offered the opportunity to enter the current pressure expressed in hPa
(mbar) in a range of 800 to 1,300 hPa. The concentration values computed by the analyzer will
then be corrected to reflect the barometric pressure or sample gas pressure resp. entry.
Input values using
and
It is possible to integrate a pressure sensor with a range of 800 - 1,100 hPa.
The concentration values computed by the analyzer will then be corrected to reflect the
barometric pressure to eliminate faulty measurements due to changes in barometric
pressure (see technical data). .
In this case it is not possible to enter pressure value manually. In attempting to enter
pressure value manually, the analyzer will automatically revert to the display of measured
pressure value.
8.2 Cross Compensation (internal)
This control permits switching the electronic cross compensation feature on and off.
The cross compensation feature is designed minimize mutual interferences between the two
gases (e. g., CO
2
and CO) measured by the analyzer.
Input value 0: cross - compensation is disabled
Input value 1: cross - compensation is enabled
