2 Clean the sensor and immerse it in the test solution.
3 Check the displayed values for the pH value and
temperature. Automatic sensing can be configured in the calibra-
tion default settings for both process variables independently of
one another. With automatic sensing, the particular influencing
variable is only displayed and can no longer be changed here.
Without automatic sensing, the particular influencing variable must
be entered manually here.
Wait until the measuring value displayed stabilizes and then check
the pH value displayed. Then confirm by pressing "OK".
Example with temperature sensing and without pH-value sensing
4 Enter the concentration value of the test solution. Confirm 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.
