WARNING: SET THE CORRECT ALTITUDE SETTING! When diving
at altitudes greater than 300 m (1000 ft), the altitude setting must
be correctly selected in order for the computer to calculate the
decompression status. The dive computer is not intended for use at
altitudes greater than 3000 m (10000 ft). Failure to select the
correct altitude setting or diving above the maximum altitude limit
will result in erroneous dive and planning data.
3.23.3 Oxygen exposure
The oxygen exposure calculations are based on currently accepted
exposure time limit tables and principles.
The dive computer calculates separately the Central Nervous System
oxygen toxicity (CNS) and the Pulmonary Oxygen toxicity, the latter
measured by the addition of Oxygen Toxicity Units (OTU).
Both fractions are scaled so that the diver’s maximum tolerated
exposure for each is 100%.
Suunto Zoop Novo does not display CNS% or OTU% but instead
displays the larger of the two in the
OLF%
field.
OLF%
value is the
Oxygen limit fraction or Oxygen Toxicity Exposure.
For example, it the diver’s maximum tolerated exposure for CNS% is
85% and the maximum tolerated exposure for OUT% is 80% the
OLF%
displays the largest scaled value, here 85%.
Oxygen related information displayed by the dive computer is also
designed to ensure that all warnings and displays occur at the
appropriate phases of a dive.
