Connect the pH probe to the instrument as shown in the electrical connections section.
Select the pH probe in the Calibration menu.
Select the second option (By Ref Calibration)
This type of calibration can be performed WITHOUT removing the probe from the probe holder, simply reading the
pH value in order to make the appropriate correction on the read measure. If a standard calibration will be
performed, the value set in this By Ref calibration, will be canceled!
