3.6. - PO2 Alarm.
The Archimede Cressi-sub dive computer is capable of mon-
itoring another fundamental Oxygen parameter: e.g. O2
Partial Oxygen Pressure (PO2).). As we have already seen,
this parameter can easily be set by the diver (Chapter3.4.1.)
with values ranging between 1.0 and 1.6 bar. The maximum
admissible Partial Oxygen Pressure is assumed to be 1.6 bar.
Depending on the type of Nytrox supply employed, it will
automatically tell you what is the maximum depth reachable.
You should never forget that even when diving with air, you
can get intoxicated with oxygen. This limit changes depend-
ing on PO2 setting. Archimede's default value is 1.4 bar, cor-
responding to a max depth with air of 183.6ft. Obviously,
other PO2 values can be set, up to a maximum of 1.6 bar.
Therefore, there are two types of PO2 alarms with your
Archimede dive computer:
1 As soon as you reach the maximum depth limit corre-
sponding to the set PO2 value ( from 1.0 bar to 1.6 bar), an
audible alarm will be sent off for 15 seconds and the
(
) icon (fig. 20) will start to blink, while the reached limit
for the PO2 setting will be blinking on the top left of the
display.
2
A second alarm will sound in any case whenever a depth
corresponding to a PO2 value of 1.6 bar is reached. The
display will blink for 15 seconds until you ascend above
the depth limit again.
Both alarms will be recorded in the Logbook.
