Test gas concentration
The zero and span test gas concentrations to be used as set points for
manual calibration need to be set for the selected sample component and
measurement range.
Calibration method
The method for manual calibration (see page 223) needs to be set.
For … Select …:
Common calibration The sample component and the measurement
ranges for zero and span calibration for the se-
lected component.
Substitute gas calibra-
tion
The (substitute gas) components for zero and
span calibration and the measurement range for
the selected component.
NOTE
The components and measurement ranges settings apply to manual, auto-
matic and externally controlled calibration.
Drift calculation
In MENU → Configure → Calibration data → Drift calculation, it
can be set if the relative drift between two calibrations is calculated only for
automatic calibration or for both automatic and manual calibration.
Only one relative drift value is saved, i.e. if an automatic calibration is con-
figured and active and a manual calibration is performed the relative drift is
calculated relative to the last automatic calibration and vice versa.
