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.
