PH Probe Calibration trouble

[LucianoB]

Hi. How are you? I have one problem with my RA+ PH Probe, past day ago My PH drop drastically, I suspected my PH Probe was working bad because one instant drop from 8.2 at 7 o minus, should be impact inmediatally in my reef.
I tried clean it and re-calibrate but something strange are happeing in my RA Display PH Calibration, the values pass at full speed without showing a fixed value.
Sometime, all the display lost the sync and the image pass at full speed. I don't know if are relate.

I tried with another New PH Probe, same thing.

Are my RA+Plus damage? Could I do something?

Thank you so much in advance.
