Not familiar with the way the Prism/Mk15 displays work - are they configured to read full scale directly from the cells (ie. 0 to 2ish PO2) or so that the set-point is on the centre of the scale with deviations shown as +/-?

I liked them too until last week when mine started telling me from all cells that I was breathing a ppo2 of over 2 bar!

No such thing as 'truly independent' electronics unless you have independent cells.

Set point was maintained correctly - but secondary display was indicating wrong ppo2
