AO2000 CONTINUOUS GAS ANALYZERS | OI/AO2000-EN REV. B 333
Temperature problem
Gas analyzer still in warm-up phase
• The duration of the warm-up phase depends on which analyzer module
is installed in the gas analyzer.

Excessive air movement
• Reduce the flow of air around the gas analyzer.
• Install shielding against drafts.
Ambient temperature outside of permissible range
• Protect the gas analyzer from cold and heat sources such as the sun,
ovens and
• Observe climatic conditions
