If PO2 continues to increase, the value displayed will increase toward a maximum value of
5.00 ATA in increments of .01 ATA.
When it reaches a value of 1.60 ATA, or the PO2 Alarm set point (a user setting), the
Audible Alarm will sound (unless set OFF) and the current PO2 value, PO2 symbol, O2
segment of the O2 Bar Graph, and UP Arrow will flash as a warning (Fig. 76) until PO2
decreases.
• Press the Front (Advance) button to view the Alternate Displays.
• The unit will revert to the Main Default Display after 3 seconds.
• Press the Side (Select) button to activate the Backlight.
HIGH OXYGEN ACCUMULATION
The O2 Bar Graph displays either oxygen accumulated during
that nitrox dive, or during the repetitive nitrox dives you conduct
during that 24 hour period, whichever of the two is greater at
that time.
The yellow
Caution Zone
of the O2 Bar Graph offers you a
convenient way to consistently monitor how close you are coming
to the limits of oxygen exposure.
Use it as a visual refer-
ence to place a wider margin of protection between
you and the Limits.
