AFTER THE DIVE
After a dive in SCUBA / GAUGE mode, the Computer stays on the SCUBA /
GAUGE screen for 10 minutes after emerging, and therefore you cannot access
the menu and submenu.
After a dive in FREE mode, the Computer stays on the FREE screen for 15 minutes
after emerging, and therefore you cannot access the menu and submenu.
After a dive in SCUBA or GAUGE mode, FREE mode is inhibited and is not
accessible for the next 12 hours.
After a dive in GAUGE mode, because tissue saturation is calculated assuming
that the dive uses mix number 1, SCUBA mode is available.
After a dive in GAUGE mode, the Desaturation and NoFly times are updated with
the new tissue saturation data. In particular, the NoFly time is set to 24 hours,
as a precaution in favor of safety, regardless of the type of profile that was run.
After a dive in FREE mode, the residual Desaturation and NoFly time, if any
existed before the dive in FREE mode, will be left unchanged.
Desaturation Time
The tissue Desaturation Time is calculated immediately at the end of the dive.
It is defined as the time necessary for the nitrogen inert gas pressure to be lower
than the Partial pressure of nitrogen (PpN2) breathed, increased by a tolerance
factor.
All calculations refer to the atmospheric pressure measured at the end of the dive.
NOTE: When using the DAN Protocol to calculate the NoFly time, for some dive
profiles it is likely that the NoFly time will be higher than the Desaturation Time,
which might not appear consistent. This is due to the fact that the NoFly time
might derive from a protocol and not from an exact mathematical calculation.
Therefore, in order to avoid creating confusion for the end user, if the NoFly
time calculated at the end of the dive is greater than the Desaturation Time, the
algorithm corrects the Desaturation Time so that it is equal to the NoFly time.
This calculation is to achieve a higher level of safety.
