PH probe calibration

[courlet]

Hi all,
Just a question to optimize the calibration: I use fluid PH 7 and 9 => with which one I should start the calibration? The lower (the 7) or the higher (9).
Maybe no impact, but just wanted to make sure.
Thanks

Hi,

before the calibration starts, you'll be asked to enter the pH-fluids. Start with the lower fluid pH7, then pH9.
