8.4.9.  Setting or changing automatic measurements 
To ensure the accuracy of measurement, the measuring instrument is continuously checked and 
corrected  during  operation.  This  is  ensured,  among  other  things,  by  automatic  operational 
calibration once a week and is shown on the display in the top line. 
 
With the factory parameterization and the commissioning settings, the operational 
calibration runs automatically without any additional intervention.  
 
Prerequisite  for  the  automatic  calibration,  which  takes  a  few  minutes,  is  that  the  operational 
calibration gas (mixture of methane + CO
2
) is permanently connected to Q2 and is at the correct 
pressure. The calibration starts with the purging time for this gas mixture, which ensures that the 
unit is filled exclusively with this gas. When calibration is complete, the measuring unit is purged 
with process gas and then automatically continues the analysis.  
During commissioning, the purge times, the gas compositions of the calibration gas and, 
if necessary, the calibration cycle must be adjusted 
Lors de la mise en service, les temps de purge, les compositions du gaz d'étalonnage et, si 
nécessaire, le cycle d'étalonnage doivent être ajustés 
 
After reading out the current parameterization, you will find the present settings  for  operational 
calibration  under  the  path  shown  in  the  picture.  This  covers  the  majority  of  applications. 
Nevertheless, it may be necessary to adjust some parameters. These changes are easier to carry out 
when using enSuite than on site at the device.

For  example,  the  exact  composition  of  the  calibration  gas  mixture  according  to  the  manufacturer's 
certificate of analysis must be checked with enSuite or on the instrument and changed if necessary, as 
shown in the picture above. The preset flushing times must also be adapted to the local conditions.
