The menu path refers to the
Externally Controlled Calibration
function block.
The zero and span calibration parameters are selected separately. Technical
Bulletin “AO2000 Function Blocks – Descriptions and Configuration” (publication
number 30/24-200 EN) contains a detailed description of the function block.
Calibration Method
The method for externally controlled calibration needs to be set for the selected
sample component (see also “Calibration Methods” section, page 8-A-10).
The zero and span calibration measurement ranges for common and substitute
gas calibration are chosen in the
Manual calibration

method
parameter.
The “Calibration method” parameter is not available in the Limas11 and Uras26
analyzer modules since the externally controlled calibration is always run as
common calibration.
Calculation Method
Select whether the calibration is to be calculated as
•
Offset calibration
•
Amplification calibration
•
Offset and amplification calibration
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.
Components for
Calibration
The sample components to be calibrated during zero and span calibration need to
be selected.
