6. pH probe calibration
Note: If you have chosen the "1-point calibration" sub-menu, the calibration must only be carried out with
the pH 7 buffer solution.
After calibration, the unit will show you the status of the probe as a %.
100%= perfect condition / 75%= good condition / 50%= fair condition, 25%= poor condition
Calibration at 1 selected point (sub-menu 1A3 "Reference" of the "calibration" menu)
The principle is to adjust the value delivered by the instrument to that delivered by a reference pH
measuring instrument (photometer...), when measuring the pH of the same solution
The pH value measured by the
instrument flashes
Adjust this value to the one
read with the reference
instrument
