Hi, I'm Kevin.
I guess I'd suggest one more test (if you're not tested out at this point). Try a dil flush on the loop before you store it for the night before a dive. Cal on Dil (not atmospheric air) and O2 then close the head and flush the loop with dil. Then do your dives and measurements.
I guess I'm wondering whether the near saturated air inside the sensors before the dive is reaching a quick dew point and causing your problems. Maybe starting with dry gas inside the sensors will help. Might be worth a try.
Good luck and let us know how your tests go.
Kevin;
I performed your test. Yesterday morning, cal'd on dil (air) using the cal-kit, closed the lid and left everything on for the day, and went on a great night dive that unfortuneately lasted only 1 hour (can't wait to get a Rebreather buddy
). Dived to 30m with EAN30 as dil and started off with 1.2's as expected. 10-15 minutes later, could only get 1.0's on dil flushes and 1.3-1.4's with O2 @6m (while buddy was deco'ing).
Getting very consistent behaviour of the sensors. They seem to undergo a change of state. I have recieved two PM's from others experiencing similiar (Meg & KISS so far). I don't see how this can be Meg specific.
I wish I could get more interest (and data) on this string.
