If you are calibrating a pH probe that is connected to the P4, you should calibrate using the P4 touch keys.

If you are trying to calibrate the KHD probe which should be connected to the KHD, you will see the option to calibrate this probe in the KH Director settings page.

...and it would be nice to have the possibility to calibrate all pH sensors in GCC

Hi Vinny,

I’m using the profilux 4, first set up i can calibrate using the touch key.
After upgrade to the latest firmware, the menu for calibration is not there.
Ph showing ph-1 virtual in the myghl.

Fyi i have profilux connect to 2x doser and connect to kh director.

Thx.
