I use two sensors for my O2 board. The third is shorted with a piece of cable between + and -.

It works perfectly when I show the small pPO2 display and shows reasonable values on sensor 1 and 2, and 0.0 on sensor 3.

When I select to show big pPO2 I only see two values of which one is always 0.0 ...

I couldn't turn it off or reset it. Tried lowering it into 2m of water, hoping the pressure change would have some effect which it ...
