CHROMIS USER MANUAL
4.7.1.7 PDI
Stops
Chromis is equipped with the innovative
Profi
le Dependent Intermediate Stops
introduced on other SCUBAPRO dive
computers.
PDI Stop optimizes the leading
compartment off gassing with a low
gradient at depth which is calculated from
the current profi le.
After the dive profi le has reached a level
where PDI Stop is recommended the
Chromis shows PDIS symbol and depth at
the top row.
If no decompression required, when
ascending to a PDI stop depth, the PDIS
symbol and depth start blinking on the top
row and a 2 minute count down starts on
the bottom row.
Once PDIS depth has been reached,
you should stay on the zone that is
-0.5m..+3.0m / -2ft..+10ft from the shown
PDIS depth. If you descend below this zone
the PDIS counter will be deactivated and
Chromis calculates a new PDIS depth.
If decompression is already required this
information remains at the bottom row. In
that case the PDIS counter is not shown but
only the PDIS symbol and depth are blinking
at the top row for the 2 minutes that are
recommended for stay at the PDIS zone.
WARNING
Even when performing a PDI stop, you still
MUST perform a safety stop at 5m/15ft for 3 to
5 minutes. Performing a 3 to 5 minute stop at
5m/15ft at the end of any dive is still the best
thing you can do for your safety.
4.7.2
No-dive warning after a dive
If Chromis detects a situation of increased risk
(due to the potential microbubble accumulation
from previous dives or a CNS O
2
level above
40%), the NO DIVE symbol will appear on
the display to advise you against performing
another dive right away. The suggested time
interval that you should wait prior to diving is
shown at dive mode display.
