Delta phase
When should a Delta
phase be adjusted?
As a rule it is done for CO, NO and SO
2
in small measurement ranges
The cross sensitivity effect of some interference components can be fine-tuned for
these sample components by adjusting a Delta phase.
This cross sensitivity alignment is only performed as needed, i.e. if the applicable
associated components are present.
In general, in flue gas applications compensation is made for 3°C H
