Hello,
Looking for others who might have experience using Aqua Lung computers for Nitrox diving?
I use an i200 computer and on two of my recent dives with Nitrox, I've noticed "O2 sat" readings of 99 in the dive log, after the dives. For other recent and similar dives, this reading has ranged between 17 and 20 (including for dives that were deeper and lasted longer than the ones where 99 was recorded). I've consulted the computer manual to make sense of this difference, but I haven't found a reasonable explanation. The manual claims a warning/alarm goes off for O2 sat of 80 or more, but I did not observe this on the dives that have later recorded an O2 sat of 99.
I've included the relevant details from the computer for recent dives (all 24h or more apart):
It doesn't seem that the readings of 99 could be accurate if they're a) so much greater than the more consistent 17-20 readings and b) exactly 99 in both cases.
I'm wondering if some condition/threshold hasn't been hit for the dives with readings of 99, but the condition/threshold has been hit for the other dives with readings of 17-20? Maybe the readings of 99 are actually O2 minutes instead of O2 saturation?
I appreciate any insight anyone might be able to share! (In the meantime, I've also contacted Aqua Lung for support).
Thank you!
