3.2.2. DIVING WITH EAN (NITROX)
3.2.2.1. BEFORE DIVING
This dive computer can be set for diving with standard air only (Air mode) or it can
be set for diving with Enriched Air Nitrox (EAN mode).
If set to the EAN mode, the correct oxygen percentage of the gas in your cylinder
must always be entered into the computer to ensure correct nitrogen and oxygen
calculations. The dive computer adjusts its mathematical nitrogen and oxygen
calculation models according to the entered O
2
% value (Fig. 3.21.). Calculations
based on Nitrox result in longer no-decompression times and shallower maximum
depths.
DEFAULT NITROX SETTINGS
In the EAN mode, the default setting is for standard air (21% O
2
). It remains in this
setting until the O
2
% is adjusted to any other percentage of oxygen (22% - 50%).
If a dive is started within 2 hours Stinger retains this value until the dive series is
finished. If unused, the computer will retain the manually entered value for the selected
oxygen percentage for about two hours, after which it will revert to the default setting
of 21% O
2
.
The default setting for maximum oxygen partial pressure is 1.4 bar, however you
are able to set it in the range of 1.2 - 1.6 bar.
