Go to the main menu, select "pH" and in the pH menu that is displayed, select
"pH +-"
Use the buttons  to adjust the required pH and confirm with "OK".
4.1.2.3.2- Calibration of the pH probe
To calibrate the probe, prepare a glass with clean water. Remove the probe
from the storage liquid, shake off the liquid and stir it in the water. Shake it
again to remove the water. Dry with a clean cloth, without rubbing.
In the control, go to "Menu" – "pH" – Calibration. The 1st line of the display
indicates "pH cal. = 7" . Submerge the probe in the pH7 solution and press OK.
A 60 seconds countdown will start (remaining time is shown on the 3rd line).
Keep the probe in the solution until it finishes.
When the countdown is finished, you will be asked to use the pH4 solution.
Remove the probe from ph7, shake off the liquid and stir it again in water.
Shake it again to remove the water and dry it with a clean cloth. Submerge it to
the ph4 solution.
Press OK and wait again for a 60 seconds countdown.
After the countdown, if the calibration is successful, a "Calibration OK" message
will be shown. Press OK to exit.
In case of getting a "calibration NO OK", the unit will keep the previous
calibration. Please check the probe conditions, and clean it or replace it if
necessary. Another cause for a failed calibration can be that the ph7/pH4
solutions are in bad conditions.
Repeat the calibration when the problem is solved.
