PH Calibration

[anash5289]

Hello, I was wondering if i need to recalibrate the ph probe if the power goes out or if I unplug the controller?

No. settings are saved in non volatile memory and only overwritten when you upload a new internal memory code or you recalibrate again.

OK i was just asking because earlier today my ph was reading 8-8.1 and i accidently unplugged the controller for less then a minute and when i plugged it back in the ph is now reading 7.8
