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 O2 Bar Graph offers you a convenient way to monitor how close
you are coming to the limits of oxygen exposure.
Use it as a visual reference to
place a wider margin of protection between you and the Limits.
