Calibration data for externally controlled calibration
Menu path
MENU → Configure → Calibration Data → Ext. controlled cal.
→ ...
NOTE
The menu path refers to the Externally Controlled Calibration function
block. The zero and span calibration parameters are selected separately. The
Technical Information "Function Blocks – Descriptions and configuration"
contains complete information on the individual function blocks.
Calibration method
The method for externally controlled calibration (see page 223) needs to be
set for the selected sample component.
The zero and span calibration measuring ranges for common- and substi-
tute gas calibration are chosen in the Manual Cal. → Calibration method
parameter.
The "calibration method" parameter is not available in the analyzer modules
Limas11 IR, Limas21 UV, Limas21 HW and Uras26 since 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 ex-
ternally controlled calibration need to be set for the selected sample com-
ponent and measurement range.
Components for calibration
The sample components to be calibrated during zero and span calibration
need to be selected.
