1) The sample gas dew point should be at least 5°C below the ambient
temperature throughout the sample gas path. Otherwise a sample gas
cooler or condensate trap is required. Water vapor can result in cross
sensitivity.
2) When there is a direct sample chamber connection the maximum sample
gas dew point is 55°C. Water vapor can result in cross sensitivity.

5) Abrupt changes in gas flow rates should be avoided when using highly
suppressed measurement ranges.

1000 hPa (1 bar)
7) Pressure resistance of the analyzer p

Note: Sample gas temperature, pressure and flow rate should be maintained
constant to such a degree that the fluctuation influence on the accuracy of
measurement is acceptable (see also Appendix 2 “Analyzer Module Operating
Specifications”).
Gas Outlet Conditions
The outlet pressure should be equal to atmospheric pressure.
