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. What can be the problem?

Could yopu please post some pictures and diagrams?

I've vaguely heard of the board and how it works but never seen one in the flesh.

Much appreciated.

Duh, a upgrade from 1.60 to 1.80 solved that.
