HH PO2 readings

sensor330 · 5th July 2006, 01:18

During my dives this last weekend of diving I had my PO2 set to 1.2 and I got average readings of 1.15 1.15 1.17 on the primary and on my secondary I notice that it was a bit higher with average readings of 1.22 1.23 1.23. When I surfaced I check both displays and they both read exactly the same at 0.68. I'm assuming that the primary is out because it constantly computing my deco profile and needs and little longer to catch up?

On the secondary the displays are constantly updated (classic mode/ it looks slightly slower in the newer modes), on the primary, the data INTERNALLY is updated frequently (from converstions I have had with kevin) but is only updated wach pass through the main display routine..

From the notes I have compiled over the years from conversations with KJ (I cant guarantee things havent changed, I just have what I was told when the system was being developed), The po2 is updated every second, the tissue loading is updated every 10 seconds, and a TTS calculation is started every 15 seconds.. I dont have notes on the frequency of the display, but judging how it reacts at the begining each pass is probably every 10 seconds, and longer as deco piles up..
