Setting the
Calibration Method
(see Figure 8-A-7)
The calibration method can be set separately for manual, automatic and externally
controlled calibration.
For common and substitute gas calibration the sample ranges for start- and end-
point 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.
