Post Dive Interval - Cochran COMMANDER Owner's Manual

A small margin shallower than the Ceiling also exists.
Should a Ceiling be 'violated' (diver is shallower than
Ceiling), the "WARNING" legend will illuminate and
flash along with the Depth and Ceiling digits. An
Audible alarm will sound once every two seconds.
This warning will continue until the Depth has been
corrected. Out-gassing will continue even though the
diver is shallower than the Ceiling. There is no
'Gauge' mode or 'Lockout' on the COMMANDER.
If the diver surfaces before satisfying his
decompression obligation, the COMMANDER will
continue to give out-gassing credit as if it were in a
dive, but at a depth of zero feet and will satisfy the
decompression time requirements of the required
stops using an FO of 21%. The unit will continue to
2
log data and perform as if actually in a dive. When the
decompression obligation is finally satisfied, the ten-
minute "Post Dive Interval" will begin.
NOTE: COCHRAN does not intend for this instrument
to be used for deliberate Decompression diving.

POST DIVE INTERVAL:

During the first ten minutes (or up to thirty minutes if
the unit is in the Training Mode) after a dive, the
COMMANDER is in the Post Dive Interval. The
flashing "SURF" legend and a Surface Time of less
than ten minutes (or up to thirty if the unit is in the
Training Mode) indicate this. Should another dive be
commenced before the completion of the Post Dive
Interval, that dive will be considered an extension of
the previous dive. In this case, Bottom Time will NOT
include the time spent on the surface in this Post Dive
Interval. However, when reviewing the profile with the
®
Analyst , the time spent on the surface in this period
will be shown.
