Suunto SS021644000 Scuba Diving Equipment User Manual


 
Diving with nitrox allows you to increase bottom times or reduce
the risk of decompression illness. However, when the gas mix is
altered or depth increased, the oxygen partial pressure is generally
increased. Suunto Zoop Novo provides you with information to
adjust your dive and stay within safe limits.
NITROX mode has the following settings
Nitrox (gas mixture)
Personal/altitude adjustment (see
3.16 Personal and altitude
adjustments
)
Depth alarm (see
3.8 Depth alarm
)
Dive time alarm (see
3.14 Dive time alarm
)
Sample rate (see
3.19 Sample rate
)
Deepstop (see
3.18 Safety stops and deepstops
)
In
NITROX
mode, both the percentage of oxygen in your tank and
the oxygen partial pressure limit must be entered into Suunto Zoop
Novo.
This ensures correct nitrogen and oxygen calculations and the
correct maximum operating depth (MOD), which is based on your
entered values.
The default oxygen percentage (O
2
%) setting is 21% (air) and
oxygen partial pressure (PO
2
) setting is 1.4 bar (20 psi).
To modify gas mix settings:
1.
While in
Nitrox
mode, keep [DOWN] pressed.
2.
Press [SELECT] to enter the
Nitrox
setting.
3. Adjust the O
2
value with [DOWN] or [UP] to match the oxygen
percentage of your tank and confirm with [SELECT].
