ALIBRATING THE P
From the CAL entry you can calibrate the pH's electrode.
Before you start, first of all you must get the accessories required to calibrate the probe (Installation kit):

Empty container that needs to be filled up with drinkable water;

pH 7.00 buffer solution (or with another value);

pH 4.01 buffer solution (or with another value);
The calibration can also be carried out with a pH 7.00 buffer solution (or with a solution with a valid pH value for the
1st calibration point), as the menu allows to calibrate the probe also for just a single point, considering the 2nd
calibration point equal to the theoretical value of 4.01 pH.
After washing the probe in drinking water, immerse it in the first solution and select the correct pH value of the
buffer solution used for the calibration (typically 7.00 pH). Then press Enter: the display will show a flashing 60-
second countdown. When this ends, the display shows the value measured in mV and the count can be interrupted
by pressing Enter.
Then, after about 10 seconds, the display shows the value of the 4.01 pH buffer solution to be used for the 2nd
calibration point: if you intend to calibrate only one point of the probe, just go to the "PEr" page (Probe Quality
Percentage) via the F key. Otherwise you need to rinse the probe in the drinking water again and immerse it in the
second buffer solution by selecting the correct pH value used for the calibration on the display.
Press Enter to carry out the second acquisition: the display will show a flashing 60-second countdown again (this
can be stopped by pressing Enter). When it ends, the display shows the measured value mV. After about 10
seconds, it displays the PEr page and with Enter, you can display the Quality of the probe expressed as a
percentage.
A Quality percentage value of the probe less than or equal to 25% means the pH probe must be replaced.
