WARNING: AERIS advocates responsible diving practices con-

sistent with your individual level of formal training and experi-

ence, and does not recommend decompression diving or diving

below 130 feet (39 m).

Oxygen Accumulation (O2) Bar Graph

NOTE: Displays associated with oxygen and the O2 bar graph

will only appear if FO2 has been set at a value other than 'Air'.

The Oxygen Accumulation (O2) Bar Graph (Fig. 5) represents oxygen loading,

your relative oxygen tolerance dosage (OTU), showing the maximum of either

per dive allowable oxygen, or 24 hour period allowable oxygen. As your expo-

sure (accumulation of oxygen) increases during the dive, segments will add to

the bar graph starting in the lower right portion of the screen. As oxygen load-

ing decreases, the bar graph will begin to recede, indicating that additional ex-

posure (accumulation) is allowed for that dive, and that 24 hour period.

The O2 Bar Graph also assists you with managing high partial pressure of oxy-

gen (PO2) by flashing the large red Danger zone segment (Fig. 5a) as a warn-

ing when the level of PO2 exceeds the maximum allowed limit of 1.60 ATA .

This is explained in detail later in the Handling the Extremes section.
