Pdis During Decompression Diving - Uwatec PDIS Manual

In LIGHT screen configuration:
The PDIS depth is shown in the MORE
sequence after the O
2
temperature. As soon as you reach that
depth during an ascent, a 2-minute
countdown will appear in place of the
no-stop value with label PDIS TIMER. You
can have one of three situations:
- you have spent 2 minutes within
3m/10ft above the indicated depth while
the timer is showing on the display.
The PDIS label and value in the MORE
sequence are replaced by the label
PDIS OK as an indication that you have
performed the PDI stop;
- you have descended by more
than 0.5m/2ft below the PDIS. The
countdown timer disappears and will
reappear again, starting at 2 minutes, the
next time you ascend to the PDIS depth;
- you have ascended by more than
3m/10ft above the PDIS. The PDIS
label and value in the MORE sequence
are replaced by the label PDIS NO
to indicate the fact that you have not
performed the PDI stop.

a missed PDI stop.
4.2 PDIS during DECOMPRESSION
diving
In C LASSIC a nd F ULL s creen c onfigurations,
upon entering decompression the PDIS
information is moved to the lower left
corner and becomes part of the MORE
sequence. This prevents the potential
misinterpretation between the PDI stop and
the decompression stop. Additionally, in
order to avoid conflicts between the PDIS
range and a decompression stop, the PDIS
depth is displayed only if it is 3m/10ft deeper
than the deepest decompression stop.
As soon as you reach that depth during an
ascent, the 2-minute countdown is initiated.
A timer as described in the NO-STOP case
is not displayed here, but the switch of the
label from PDIS to PDIS OK alerts you
when the timer has reached 2 minutes.
