3 Enter the concentration value of the first reference solution in per-
cent. Confirm by pressing "OK".

Wait until the measuring value displayed stabilizes and then con-
firm the result of the measurement by pressing "OK".
5 As in step 3, enter the concentration value of the second solution
in percent. Confirm by pressing "OK".
6 Clean the Redox electrode and immerse it in the second
test solution. Wait until the measuring value displayed stabilizes
and then confirm the result of the measurement by pressing "OK".
7 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.
