7. Redox probe calibration
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 1B2 "Reference" of the "Calibration" menu)
The principle is to adjust the value delivered by the instrument to that delivered by a reference redox
potential measuring instrument, when measuring the redox of the same solution.
