Shearwater Petrel
Advanced Configuration 2
This section allows changing of PPO2 limits�
Warning
: Do not change these values unless you understand the effect�
All values are in absolute atmospheres [ata] of pressure (1 ata = 1�013
Bar)
OC Min. PPO2
PPO2 displays in flashing red when less than this value. (Default 0.19)
OC Max. PPO2
PPO2 displays in flashing red when greater than this value. (Default
1�65)
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)
Note: Semi-closed (SC) PPO2 alarms and gas switch depths use the
OC values�
CC Min. PPO2
PPO2 displays in flashing red when less than this value. (Default 0.40)
CC Max. PPO2: PPO2 displays in flashing red when greater than this
value� (Default 1�60)
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�
