6. After the run-in time set the following gas flows:
set such that in the window STATUS ANALYZER the value
N
OMINAL = 100 ± 5 is displayed
corresponds to approx. 1.7 l/min
2.3 – 2.5 l/min
The analysis system now has time for conditioning.
If the intake flow differs greatly or changes subsequently, re-adjust it at the "pump"
