NOTE:
- The
LIGHT confi guration does
not support diving with more
than one gas mixture. If you have
chosen the
LIGHT confi guration
and you set more than one gas
mixture, the screen confi guration will
automatically switch to
CLASSIC
during the dive.
- The LIGHT confi guration does
not support dives with level
stops or decompression stops.
If you have chosen the
LIGHT
confi guration and you enter level
stops or decompression, the screen
confi guration will switch to
CLASSIC
until you have fulfi lled all level stop
and/or deco stop obligations.
2.9.2 Language
In this menu you can set the language used
for all texts displayed on the computer.
2.9.3 Start-up picture
(default: Galileo logo)
Galileo allows you to choose a picture
that will be displayed for 8 seconds upon
turning on the computer. In this menu you
choose the picture from those available in
the computer memory.
2.9.4 Units
You can choose to have the depth
displayed in meters or feet, the temperature
in degrees Celsius or degrees Fahrenheit
and the tank pressure in bar or psi.
2.9.5 Workload (default: HEART)
At the base of any decompression
calculation there is the transport of nitrogen
from the lungs to the blood and from there to
the tissues during ongassing, and the same
again in reverse during offgassing. As such
it is obvious that the single most important
parameter in a decompression calculation is
the rate at which blood travels through the
body. During heavy exercise, the total blood
fl ow from the heart can be up to 4 times
higher than while at rest. This increase in
blood fl ow is rather unevenly distributed, with
some tissues such as the Central Nervous
System and the brain being unaffected,
while others like the muscles receiving up to
ten times more blood than at rest.
UWATEC introduced workload-induced
decompression algorithm compensation in
1995 with the Aladin Air X dive computer.
The workload estimation was based on
changes in the breathing pattern as detected
by the hoseless high pressure transmitter,
and the decompression calculation in four
of the 8 compartments in the ZH-L8 ADT
model was changed accordingly.
Galileo is the fi rst dive computer to have an
integrated heart rate monitor, based on world
leading heart rate monitor technology by Polar
(for Galileo to receive heart rate information,
you must wear the Polar T31 coded transmitter
as described in section 1.13). The heart rate
is directly linked to the pumping action of the
heart, and as such it is a more direct indicator
of workload than respiration.
