3.5 Calibrate single Analyzers/ Analyzer Modules/ MLT Channels
Each specific analyzer has still the possibility to start a calibration over other instances than
SYSCAL. For this functionality we now have some additional considerations.
SYSCAL. For this functionality we now have some additional considerations.
•
Do not start a calibration of a single AM or MLT channel during a running SYSCAL.
This will confuse the valve switching and the calibration commands of SYSCAL. Therefore
look also for all automatic start instances of an analyzer.

•
A single calibration cannot use the purge times of system valve settings. Instead of we
have to setup the AMs own parameters in the manner to wait for the required purge time
after a valve switching.

•
It is refused to start single calibration of a second AM if the needed calibration gas valve is
also any calibration gas valve of the first started AM.
also any calibration gas valve of the first started AM.
These considerations are valid for all AMs which are included into SYSCAL.
