• Manual calibration offset
Enter starts the calibration procedure.
After reaching a stable level for the span gas concentration
(line 2 displays the current value), pressing the Enter key
closes the calibration procedure. The analyser jumps auto-
matically into the measurement level.
A fault during the calibration is represented on the display
as
E ... followed by the message: O
2
-calibration.
The calibration fault is also stored in the calibration log-
book.
• Autocalibration offset
Enter starts the procedure.
The calibration procedure happens automatically.
The analyser is purged with span gas. The purging time
which counts backwards is setted in menu point12.5.6
The next step is calibrating the analyser with span gas. The
calibration time is setted in menu point 12.5.6.
The time counts backwards. After reaching a stable value
the time steps double.
In the following the analyser is purged with sample gas for
the time mentioned above.
When the calibration procedure is finished, the analyser
jumps automatically into the measurement level.
A fault during the calibration is displayed as:
E ... O
2
-calibration, and is also stored in the calibration
log-book.
• Autocalibration
Enter starts the calibration. The times for purging and
calibration are setted in menu point 12.5.6.
First the analyser is purged with zero gas.
Then the analyser is calibrated with zero gas.
The same procedure happens with span gas.
