3.2.2.4. OXYGEN LIMIT FRACTION (OLF)
In addition to tracking the diver’s exposure to nitrogen, the instrument tracks the
exposure to oxygen. These calculations are treated as entirely separate functions.
The dive computer calculates separately for Central Nervous System oxygen
toxicity (CNS) and Pulmonary Oxygen toxicity, the latter measured by the addition
of Oxygen Toxicity Units (OTU). Both fractions are scaled so that the maximum
tolerated exposure for each is expressed as 100%.
The Oxygen Limit Fraction (OLF) bar graph has 7 segments, each representing
12,5% (from 1 to 50%) or 15% (from 50% to 80%). The OLF bar graph displays
only the value of the higher of the two calculations. When the OTU value meets
and exceeds the CNS value then in addition to displaying its percentage the lowest
segment blinks to indicate that the value shown relates to OTU. The oxygen
toxicity calculations are based on the factors listed in chapter 7.3. “Oxygen
Exposure”.
