Smart dive computers

VII

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 – 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.
