Setting the calibration method
The calibration method can be set separately for the three types of calibra-
tion control (manual, automatic and external).
For common and substitute gas calibration the sample ranges for zero and
span calibration of all three types of calibration control are adjusted jointly.
For substitute gas calibration the zero and span calibration components
should also be set.
