Oceanic Personal Dive Computer Veo 100Nx ユーザーズマニュアル

The Pre Dive Planning Sequence (PDPS), which appears after

Surface Mode prior to the first dive of a new activation period,

provides a sequence of theoretical dive times available for

depths ranging from 30 FT (9 M) to 190 FT (57 M) in 10 FT (3

M) increments.

No decompression times (limits), or NDLs, are only displayed

for depths where there is at least 3 minutes of theoretical dive

time available at the depth, taking into account a descent rate of

60 feet (18 meters) per minute.

The PDPS should be reviewed prior to every dive to help you

plan your dive as required to avoid exceeding no decompres-

sion or oxygen exposure limits.

For repetitive dives, the PDPS indicates adjusted dive times that

are available for the next dive, based on residual nitrogen or

oxygen accumulation (whichever is in control) following the last

dive and surface interval.  It appears after the SAT screen in the

scrolling Surface Sequence (SURF > FLY > SAT > PDPS).
