3 Preparation for the dive

III UWATEC

Smart dive computers

3.1 Setting the gas mixture and MOD

Before every dive and after changing the tank, make sure that the settings for the

gas mixtures correspond with the current mixtures used.

An incorrect setting cau-

ses TEC to miscalculate this particular dive. If the fraction of oxygen is set too

low this can lead to oxygen poisoning without warning. If the value is set too

high decompression sickness may occur.

Inaccuracies in the calculations are carried

over to repetitive dives.

For dives with a single gas mixture, assign the gas mixture to tank symbol 1 and shut off gas mixtures

2 and D. ->34

If more than one gas mixture has been selected, TEC will display at the surface and the number of

gas mixtures.

For dives with several gas mixtures please read pages 32 and 13 for further reference.

To set the gas mixture, TEC must be in user mode.

1. Press to choose the tank for the O

mixture you are going to enter. The

tank symbol will start flashing. Press and hold to confirm your selection.

2. Bridge contacts B and + or B and – until the symbol for the setting of the

mixture appears.

3. Confirm that you wish to change the displayed oxygen fraction by bridging

B and E.

4. Change the oxygen fraction in increments of 1% by bridging B and + or B

and –. TEC will display the current fraction of oxygen, the maximum parti

pressure limit, ppO

max (as pre-set by means of SmartTRAK) and the MOD

5. Confirm the selected percentage with B and E.

6. By bridging B and + or B and – you can change the

MOD for the chosen fraction of oxygen. TEC will now

display the corresponding partial pressure limit (pp

max) for the new MOD.

7. Confirm your MOD settings with B and E.

•

Without confirmation the display will disappear after 3 minutes and your entries will not be

accepted.

•

Please refer to page 32 for the setting of gas mixtures for tanks 2 and D.

• The time to reset the O

% mix to air can be set with SmartTRAK between 1 and 48 hours

or to "no reset" (default).

3.2 Setting the MB level See chapter V, ->28

3.3 Preparation for diving with more than one gas mixture See chapter VI, ->32

3.4 Preparation for the dive and function check

The following descriptions of the preparation are based on the assumption that all transmitters have been

correctly mounted at the HP outlet of the regulators (->12) and successfully paired with TEC (->13).

1. Mount the regulator together with the transmitter on the tank

2. If present, check the reserve valve of your tank, the reserve valve must be

open.

3. Switch on TEC (B-E) and check the test display: Are all elements of the dis-

play activated? Do not use TEC if the display does not show all elements.

4. Open the valve (transmitter will switch on automatically) and check the tank

pressure (after approx. 10 seconds). If the pressure is insufficient, change the

tank.

5. Check the connections and instruments for leaks. Never dive with leaky

equipment!

Repeat 4 and 5 with all transmitters you are going to use.
