4.2.3.5 Wait for Finishing Calibration
Any AM has the LON-variables
• CALSTAT
Whether the selected AM is still calibrating or not, is checked by reading the variable
CALSTAT.
This CALSTAT-check is done in time intervals. During the intervals time is given to other
tasks.
4.2.4 Finishing System Calibration
After system calibration was working through the sequence buffer or it was canceled there is
to do some finishing work.
• Actualize some displayed LON-variables
• Look for some still running calibrations in case of cancelling and cancel them, too.
• Restore modified LON-variables of AMs.
• Switch system valves to sample gas state for all AMs
• Cause to set any AM’s LON-variable PROCESS = "valid sample gas" after purging time of
sample gas valve.
