NOTE: barometric pressure is a
variable, changing with weather and
atmospheric pressure at a specific
elevation. Dive algorithm uses Altitude
Classes which are directly derived
from the barometric pressure. Altitude
is counted from the current barometric
pressure and it is therefore a relative
value.
The altitude can be adjusted when current
elevation is known by pressing the SEL/ESC
button. The altitude value will start flashing.
By pressing +/UP or –/DOWN buttons
the value can be adjusted in 10m/50feet
increments. Adjusting the altitude elevation
has no effect on Altitude Class.
F
NOTE: Different altitude/temperature
measurement combinations such as
m&˚C, Ft&˚C, m&˚F or Ft&˚F can be
selected from the dive mode menu in:
Units.

Planning a dive
You can plan your next dive based on your
body’s nitrogen saturation. The planner
also uses the following information:
1. Selected oxygen concentration and
active tanks
2. Selected water type
3. Selected microbubble level
4. Water temperature of the most recent
dive
5. Altitude class
6. Status of saturation at the time the plan-
ner is started
7. A normal workload of the diver and
observance of the prescribed ascent
rates.
By pressing SEL/ESC button at the planner
menu you will get into the planner directly
or to the surface interval setting (repetitive
dive).
F
NOTE: When Meridian is in GAUGE or
APNEA modes the Planner is disabled
and Planner OFF is shown in this
menu.
Prohibited Altitude Class
Surface interval
Surface interval
For repetitive dives enter the surface
interval: By pressing the +/UP or –/DOWN
buttons the surface interval can be adjusted
in 15 minutes increments. The prohibited
altitude is shown on the top row and by
increasing the surface interval the allowed
limit will get to maximum (level 4).
In case Meridian is displaying the no-dive
warning, the duration of the warning itself is
displayed as recommended surface interval
for planning purposes (rounded up to the
nearest fifteen-minute increment).
