Edit gas

When diving with nitrox gas mixture, both the percentage of oxygen in your tank and the oxygen partial pressure limit must be entered into Suunto Nautic S. 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 (O2%) setting is 21% (air) and the oxygen partial pressure (ppO2) setting is 1.4 bar.

You can modify the oxygen percentage and the partial pressure of the active gas in the Edit gas view by selecting the mixture.

modify mixture

The oxygen fraction can be modified between 21% and 100%.

The ppO2 setting limits the maximum operating depth (MOD) to which the gas mixture can be safely used. You can set the ppO2 value to 1.0, 1.1, 1.2, 1.3, 1.4, 1.5 or 1.6.

NOTE:

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

In the Edit gas menu you can also set your tank size. The default value is 12 liters / 80 cu ft. Make sure you set your correct tank size to ensure correct gas consumption calculations when diving with Suunto Tank POD.
