MULTIPLE TISSUE TRACKING
AERIS dive computers track 12 tissue compartments with halftimes ranging from 5 to 480
minutes. The NIBG displays the controlling compartment, the one important at that time.
Think of the NIBG as 12 separate transparent displays laid on top of one another. The tis-
sue compartment that has filled up fastest is the only one the diver can see from the top.
At any particular point, one tissue compartment may be absorbing nitrogen, while another
that was previously higher may be off-gassing.
NOTE: This feature is the basis of multilevel diving, one of the most
important contributions that an AERIS dive computer offers you.
NO DECOMPRESSION LIMITS
Refer to the tables in the Operating Manual provided with your specific dive computer for
No Decompression Limits for various altitudes. Note that the NDLs do not extend beyond
the limit to which the range of the specific dive computer's Pre Dive Planning Sequence, a
maximum of either 160 FT (48 M), or 190 FT (57 M).
When the Conservative Factor feature is set On, the NDLs which are based on the algo-
rithm selected and used for Ni/O2 calculations and displays relating to Plan and DTR,
will be reduced to the values available at the altitude level that is 3,000 feet (915 meters)
higher. Refer to the NDL charts in the back of the Operating Manual.
