I've had a couple of cells that seemed to loose calibration on longer dives, drifted to 0.2 below other cells. O2 flush at 6m & they only made it to 1.4. Once head dried out, they calibrated OK & worked OK for 90mins to 2 hours.
When doing 2 dives, cell caused "must calibration" when unit turned on for 2nd dive rather than the more usual "calibrate?". However, more noticeable on longer 3 hour dives.
One cell replaced by AP, the other is currently in my spares kit.
Replacing cell fixed issue.
Hope this helps

Thanks for the info. I am hoping that AP will replace the cells and that will be all that is needed. Should here back tomorrow
