OK, done all stages and millivolt reading does not change. Once unit is calibrated to 98% and I breath off the loop the reading does not change. either port is stuck on vr3 or cell has gone very wrong. so...I changed the cell and no change, still gives me the exact same mV rating, surely that can't be correct.
Going to give up for this evening and try again tomorrow.

Hi Mark,
I have been having a similar problem with mine. No matter whether I calibrate in air or 98% there is still a difference in the PO2 reading. I dived it once and had all sorts of warnings after the PO2 reading went sky high once I was at depth, so I changed back to fixed setpoint and continued the dive without incident.
I emailled AL Wright at Deltp P and he was very helpful. After I did all the checks he suggested he then said it was best to send it back and have it checked over which I now plan to do.
I am running an earlier software version so I will get it updated at the same time.
