oxygen concentration (O

%) will be
highlighted. Underneath the O

% you can
see the ppO

and the corresponding MOD.
After changing the oxygen concentration,
the ppO

change its value between the maximum
allowed value (see section 2.3.4) and
1.0bar
. As you change the ppO
2
value, the
MOD changes accordingly. Note that the
MOD is also a function of water type (salt
or fresh) and of atmospheric pressure (and
hence altitude).
