Apnea Mode - Uwatec Meridian Manual

3.13 APNEA mode
Meridian has an advanced APNEA diving
mode. The main features include faster
sampling rate than in normal SCUBA mode
and alarm functions tailored to APNEA
diving.
Meridian measures the depth in APNEA
mode every 0.25 seconds to ensure the
precise maximum depth. In logbook the
data is saved in 1 second intervals. The
higher amount of saved data requires
more space and the consequence is that
approx 10 hours of log data can be stored
in APNEA mode.
In APNEA mode it is also possible to start
and stop the dive manually by pressing the
–/DOWN button. This way you can use the
meridian for static APNEA dives, where
normal dive start depth of 0.8 meters will
not start a new dive.
As with GAUGE mode, Meridian doesn't
carry out any decompression calculation.
You can only switch to APNEA mode if the
dive computer is completely desaturated.
APNEA mode at surface after a dive
shows the maximum depth and the dive
duration (4 minutes 47 seconds in the
example below) at top row. In the middle
row the surface interval counter is counts
15 minutes and if no repetitive dive is done
the Meridian turns to APNEA menu display.
On the bottom row the sequential number
of APNEA dives on this session is shown.
