4.6 Calibration of pH electrode
The calibration of the pH electrode is carried out on two points, therefore it is requested to have the following
material always available:
 pH 7 buffer solution.
 pH 4,01 buffer solution.
 Container with water for cleaning the electrode (i.e. a glass).
Select the option pH Calibration from the installer menu and follow the instructions displayed.
Once carried out the pH 7 calibration, rinse the electrode with water, so to prevent the pH 4 solution
from polluting.
Once the procedure is completed, the quality of the calibrated electrode will be displayed; if the quality of the
probe results 25% or less, carry out a new calibration.
Should the result still be 25% or less, it is recommended to replace the probe.
4.7 Calibrating the redox electrode
The calibration of the redox electrode is carried out only on one point, therefore it is requested to have the
following material always available:
 475 mV buffer solution.
Select the option Rx Calibration from the user menu and follow the instructions displayed.
Once the procedure is completed, the quality of the calibrated electrode will be displayed; if the quality of the
probe results 25% or less, carry out a new calibration.
Should the result still be 25% or less, it is recommended to replace the probe.
