Can anyone talk me through how to Cal My Ph probe on my P2?

Thanks

[this is me]

I have a P3 but I assume they are the same for cal procedure.
You have to do it on the controller itself and not through Profilux Control software. It usually requires you to sink your probe into a low PH solution and then a high solution.
