Good question. I am attempting to figure how to read this properly but there is not much of anything about this unit.
Videos tell nothing
Is this normal for every unit? Mine does the same.
I 3rd that result. Followed instructions to the letter and after 4 months the PH reading is no longer accurate, no longer stable(slowly fluctuates whole points, never settles on 7.0 for ex) and flashes r1,5 every power up, just for a moment.

My instrument shows an r1,5 in the screen.
What does that code mean?
