3 Check that the "Redox test solution" value displayed matches the
Redox value of the test solution.
The "Redox test solution" value is taken from the calibration default
values. It is still possible to change this manually here.
4 Clean the Redox electrode and immerse it in the test solution. Wait
until the measuring value displayed stabilizes and then confirm the
result of the measurement by pressing "OK".
5 A protocol summarizing the calibration values determined then ap-
pears. Acknowledge the protocol by pressing "OK".
Failed calibrations are canceled at this point and discarded.
6 Press "Yes" to accept the calibration values determined and enter
the calibration in the calibration logbook.
Press "No" to discard the results.
