PPO2 Limits

This section allows changing of PPO2 limits.

All values are in absolute atmospheres [ATA] of
pressure
(1 ATA = 1.013 Bar)

OC Low PPO2

PPO2 displays in flashing red when less than this
value.
(Default 0.19)

OC MOD. PPO2

PPO2 displays in flashing red when greater than this
value on the bottom phase of the dive. (Default 1.4)

OC Deco. PPO2

The decompression predictions (TTS and NDL) will
assume that the gas in use at a given depth is the gas
with the highest PPO2 that is less than or equal to this
value. Also, the suggested gas switches (when the
current gas is displayed in yellow) are determined by
this value. If you change this value, please understand
its effect. For example, if lowered to 1.50, then oxygen
(99/00) will not be assumed at 20ft/6m. (Default 1.61)

PPO2 displays in flashing red when greater than this
value during the deco phase of the dive (within 25ft /
7.6 m. of the next deco stop).

CC Low PPO2

PPO2 displays in flashing red when less than this
value.
(Default 0.40)

CC High PPO2

PPO2 displays in flashing red when greater than this
value.
(Default 1.60)

Reset Limits

Resets all PPO2 limits for this dive mode back to
defaults.

Note:

In both OC and CC mode, a “Low PPO2” or

“High PPO2” alert is displayed when the limits are
violated for more than 30 seconds.

WARNING

Do not change these values unless
you fully understand the effect.
