Action: Service calibration 
Connect the first gas (offset gas to 
correct the measurement offset) to the 
selected gas inlet correctly and click on 
“Confirm”. 
The procedure will then start 
automatically. First of all, the system is 
flushed with the calibration gas mixture. 
This will be displayed throughout the 
duration of the process. 
 
Then the first service calibration gas 
(offset gas) is measured.  
 
The duration of this process will also be 
displayed. 
 
If you want to cancel the process prematurely, you can end the calibration after point 4 by 
selecting “Cancel”. The measurement device will then interrupt the calibration process and 
will ask you to take further action to return to analysis mode. 
After measuring the first gas (offset gas), 
the following display will appear and will 
initiate the second part of the calibration. 
Select “Next”.
