TEC has a dive planner which allows the planning of no-stop dives as well as decompression dives with
freely determinable surface intervals and with up to three different gas mixtures.
• selected fraction of oxygen and MOD of all active gas mixtures
• selected microbubble level
• water temperature of the most recent dive
• altitude range (if any)
• status of saturation at the time the dive planner is selected
• assuming a normal workload of the diver and observance of the prescribed
ascent rates
• assumption: changes of gas mixture are performed at the selected MOD of
mixtures 2 and D.
If two or more divers using computers are planning a dive, planning for all
divers has to be based on the dive computer showing the shortest no-stop
times. Failure to do this may lead to serious injury or death from decompres-
sion sickness.
Before using the dive planner, the fraction of oxygen must be entered for each required tank and the
depths for a change of gas mixture for tanks 2 and D must be entered. Tanks, i.e. gas mixtures which are
not going to be used during the next dive must be switched off (->33-34). All 'activated' gas mixtures will
be indicated by their tank symbols and allowed for calculation.
1 Planning a no-stop dive
With the contacts B and – or B and + you can select the dive planner at the
surface. (The dive planner cannot be selected in gauge mode)
The microbubble warning and
its duration are displayed if
TEC detects an increased risk
due to the accumulation of
microbubbles.
Enter the dive planner with B and E.
The input window for the time interval is displayed
if there was a remaining desaturation (DESAT) befo-
re the Dive Planner has been selected. This surface
interval between now and the beginning of the dive
can be changed with the contacts + and – in steps
of 15 minutes.
If a microbubble warning (no dive) and its dura-
tion has been displayed, TEC proposes this time –
rounded up to the next 15 minutes – as surface
interval. If the proposed interval is shortened, the
microbubble warning appears.
With B and E you confirm the displayed interval (if applicable), then TEC starts
scrolling the no-stop times. The no-stop times are displayed in 3 metre incre-
ments (10 ft) and are displayed for every increment for about 2 seconds. The
process starts at 3 metres (10 ft).
If a microbubble level has been selected (L1-5), the MB no-stop time is
shown.
No-stop times will be displayed as long as the selected maximum operating
depth (MOD) of tank 1 is not exceeded.
On page 24 you will find further information and safety considerations
regarding the microbubble warning.
