Notes
1
Analyzer calibration against CGM may be cancelled prior to operation 4,
depressing the key
. The analyzer shall go over to the display shown in
Fig. 2.15 and save calibration coefficient values of the previous calibration.
2
If a salt content value was entered prior to change to the manual
calibration mode, the analyzer shall be calibrated with regard to salt content.
2.3.5.2 Analyzer calibration against solution with known DOC value
Calibration against solution with known DOC value is to be undertaken if, for
instance, a reference dissolved oxygen analyzer is available. In this case DOC in
the same solution is to be measured by the reference and working analyzers. Wait
for stable readings of both analyzers.
Press the key
. The display shown in Fig. 2.21 shall come up.
