If decompression is already required this
information remains in the middle row. In
that case the PDIS counter is not shown
but only the PDIS symbol is flashing for the
2 minutes that are recommended to remain
in the PDIS zone.
WARNING
Even when performing a PDI stop, you still
MUST perform a safety stop at 5m/15ft for 3 to
5 minutes. Performing a 3 to 5 minute stop at
5m/15ft at the end of any dive is still the best
thing you can do for yourself!
3.12 GAUGE mode
When Meridian is set to GAUGE mode, it will
only monitor depth, time, and temperature,
and will not carry out any decompression
calculations. You can only switch to
GAUGE mode if the dive computer is
completely desaturated. All audible and
visual warnings and alarms, other than the
low battery alarm, are turned off.
WARNING
Dives in GAUGE mode are performed at your
own risk. After a dive in GAUGE mode you must
wait at least 48 hours before diving using a
decompression dive computer.
When on the surface in GAUGE mode,
Meridian will show neither the remaining
desaturation time nor the CNS O
2
% value.
It will however display a surface interval up
to 24 hours and a 48 hour no-fly time. This
no-fly time is also the time during which
you cannot switch back to dive computer
mode.
The GAUGE mode surface display after a
dive shows the dive time at the top row.
In the middle row the stopwatch is running
from the dive start or last manual restart. On
the bottom row the maximum depth of the
dive is shown. After 5 minutes timeout the
display changes to GAUGE menu mode.

Max depth Stopwatch
During a dive in GAUGE mode, Meridian
displays a stopwatch in the middle row. This
can be reset and restarted by pressing +/
UP button.
While in GAUGE mode, the average depth
can be reset. To reset the average depth,
press and hold –/DOWN button
Similarly to the regular dive computer mode,
press and hold button +/UP to view the
time of day for 5 seconds in the middle
row and other alternative information at
the bottom row. In the display below the
time of the day has been selected and it is
