Calibration Data for Externally Controlled Calibration
Menu Path MENU → Configure → Calibration data →
Ext. controlled cal. → ...
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 → 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.

Response
Signals at the current outputs (analog outputs)
• Are held at the last measured value prior to starting calibration or
• Can follow measurement value changes during calibration.
