Planning A Dive - SCUBAPRO-UWATEC Chromis User Manual

3.2.6

Planning a dive

You can plan your next dive based on your
body's nitrogen saturation. The planner is
also using the following information.
1. Selected oxygen concentration.
2. Selected water type.
3. Selected microbubble level.
4. Water temperature of the most recent
dive.
5. Altitude range.
6. Status of saturation at the time when the
planner is started.
7. Observance of the prescribed ascent
rates.
By pressing the SEL button in the planner
menu you will get into the Planner directly
or to the surface interval setting (repetitive
dive).

NOTE: When Chromis is in GAUGE or
APNEA modes the Planner is disabled
and this is indicated by showing OFF
in this menu.
In case you plan to make a second dive
during the desaturation phase, you must
start the Planner by inputting the time you
would still stay at the surface.
CHROMIS USER MANUAL
By pressing the + or – buttons you can
set the time in 15 minutes increments. The
prohibited altitude is shown at middle row
and by increasing the surface interval the
allowed limit will get to maximum (level 4).
You may read more about the altitude
diving with Chromis in the chapter Altitude
diving.
In case Chromis 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 fi fteen-minute increment).
When the surface interval is given or if you
have no remaining desaturation left, the
planner will start blinking the depth. By
pressing + or – you can set the depth in
3m/10feet increments.
The no decompression dive time is shown
for that depth at the bottom row.
The gas O content is shown at the top row
2
until the 1% CNS for the planned depth has
been reached. After that the planner shows
the CNS% at the top row.
Minimum depth for planning is 9m/30feet.
The planner allows only depths according
to maximum ppO . The gas oxygen content
2
and maximum ppO settings are given at
2
the dive set menu: GAS.
