GAA610-M ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B
Automatic calibration
Definition
Automatic calibration means:
Calibration with internal gas filled cells and ambient air. Zero and
span calibration run automatically after starting. No test gas is
required for the normal automatic calibration. During automatic
calibration, the system runs on ambient air.
Starting automatic calibration
Automatic calibration can be started in two ways:
•
At time intervals determined by the internal clock
•
Manually via the display and operation unit of the gas
analyzer
In the following the start is described in detail.
Internal start
Automatic calibration is normally started cyclically on a time-
controlled basis by the internal clock of the gas analyzer.
The cycle time and the start time of the automatic calibration
can be adjusted in the menu 'MENU / Configure / Calibration
Data / Automatic Calibration' (Password: 081500).
By default, a zero and endpoint calibration is performed daily at
7:00 am.
Manual start
Figure 36: Control page
The automatic calibration can be manually started on the display
and control unit. The easiest way to start the automatic
calibration manually in the GAA610-M is from the control page.
You can find them in the overview by changing the pages with
'>>'.
When you reach the control page, you can start the calibration by
pressing key 6. You can also deactivate the automatic calibration
here. If this option is activated, the automatic calibration is no
longer performed.
You can also start the automatic calibration from the menu
'MENU / Calibrate / Automatic Calibration / Zero & span cal.'
It is also recommended to perform the zero & end point
calibration here.
Message display
Figure 37: Status message 'Autocal Running'
During automatic calibration an 'Autocal Running' message
blinks in the softkey line.
The calibration is completed. This can be checked in the logbook
'MENU → Diagnostic/Information → Logbook'. The logbook
saves the last 500 events.
