4.1. – Data processing.
This chapter deals with all the “on surface” functions, inclu-
ding data processing after a dive, both in and in
programs. By depressing button B (Mode), it is possible to
track the following functions: ( )- logbook (please see
chapter 4.1.2.). ( ) – dive history memory (please see
4.1.3.). ( ) - Dive profile (please see chapter 4.1.4.). Data
PC transfer by means of the interface (optional) (please see
chapter 4.1.5.).
4.1.1. – Surface interval.
After a dive in program (a depth greater than 5 ft.), the
UFDS display will offer the following information (picture 25):
1 De-saturation time, given in hours and minutes by the
( ) icon;
2 “Don’t Fly” ( ) icon.
If the “Don’t Fly” icon is displayed, flights or travel to higher alti-
tudes than the current altitude must be avoided, so long as it
is visible on the display.
WARNING: DAN (Divers Alert Network) and UHMS
(Undersea and Hyperbaric Medical Society) advise a surfa-
ce interval time of between 12 and 24 hours for no decom-
pression dives, and a surface interval of 48 hours after a
decompression dive or especially fatiguing dives.
3 Surface time ( ), displayed in hours and minutes,
means the current surface interval time.
4 graph showing the tissues residual nitrogen after the dive.
NOTE: Should a dive begin with less than 10 minutes of sur-
face interval time, Archimedes II will consider this a conti-
nuation of the previous dive; the dive’s count and dive time
computation will restart from where they had stopped.
NOTE: Dives carried out after at least 10 minutes of surfa-
ce are considered as a new dive.
Should the dive be carried out in or depth meter/timer
program, the computer will not supply any data relating to
de-saturation and will process any saturation and de-satura-
tion computations during the following 48 hours elapsing
from the program dive. They are given by the surface
time (SURF T) icon, in hours and minutes, which indicates the
current surface time (picture 26).
By depressing button B (Mode) twice, you view to the dive
planning program, represented on the UFDS display by
( ) icon (picture 5b), as seen in chapter 2.4. It will take
into account the residual tissues’ nitrogen, and will modify the
no decompression time, making them shorter than those
given for the first dive.
NOTE: PLAN function does not function in compu-
ting program (depth meter/ timer).
At the end of de-saturation, the lateral bar, representing the
residual nitrogen, will be empty, representing the full elimina-
tion of residual nitrogen that may affect following dives.
