PH Climbing

[maineultraclassic]

I have my PH probe disconnected so I can give it a cleaning, it's soaking in vinegar right now.
All day today my PH has climbed up to 10.59, with nothing connected. In the past it has read 0 while nothing is connected.

Is this a sign something funky is going on with the board?

I'm going to reconnect it this evening.........curious to see what the reading does.

pH readings without a probe are just reading whatever noise is in the air... lol
It's normal to go either up or down.

Looks like it is back to normal..........just thought it was weird that it just climbed up where in the past it read 0.00.
