If displays shown in Fig. 2.6 and Fig. 2.7 have come up, refer to 2.6
"Troubleshooting".
After calibration the analyzer is available for operation.
Note
− Analyzer calibration against atmospheric air may be cancelled prior
to operation 5 depressing the key
. The analyzer shall go over to the
measurement mode and save calibration coefficient values of the previous
calibration.
2.3.5 Analyzer calibration against GSO CGM with known oxygen content in
% vol. or against a solution with known DOC value ("
manual
")
This calibration is undertaken additionally to reduce inaccuracy of
measurements. Analyzer GSO CGM calibration is to be carried out either against a
solution with known DOC value or oxygen content close to the values measured.
Prior to manual calibration, an automatic calibration against atmospheric air
is recommended.
2.3.5.1 Analyzer calibration against CGM
Prior to calibration the meter is to be held at room temperature for at least
1 h with AA alkaline dry cells or AA metal hydride batteries.
For calibration assemble the package in compliance with Fig. 2.14.
