Diving with microbubble levels
3 Preparation for a dive with microbubble levels (MB levels)
3.1 Setting the MB level
To change the MB level XP AIR must be in user mode.
1. Bridge contacts B and + or B and – until the symbol for MB levels
appears.
2. Confirm that you wish to change the displayed MB level by bridging B
and E.
3. Change MB level by bridging contacts B and + or B and – .
4. Confirm with B and E the selected MB level.
Without confirmation the display will disappear after 3 minutes and your
entries will not be accepted.
XP AIR will display the
symbol to confirm that an MB level beyond L0
(L1-L5) has been chosen. If however a level stop is ignored, the new MB
level is permanently shown (->32).
F
MB levels have an influence on the dive planner.
4 Functions during the dive with microbubble levels
4.1 Level stop information
Microbubble (MB) no-stop time
While diving with MB levels L1 to L5 XP AIR will display the MB no-stop
time instead of the ordinary no-stop time. Within the MB no-stop time no
level stops are required.
The arrow
NO STOP
and the MB level symbol
are visible. The remaining
MB no-stop time is shown in minutes.
• Information and alarms for MB no-stop time and ordinary no-stop time
are the same (->23).
• Regardless of the MB level, we generally recommend to perform a slow
ascent during the last few metres / feet.
level stop
On entering the level stop phase, the arrow
NO STOP
disappears and the
arrow
LEVELSTOP
appears. The
LEVELSTOP
arrow flashes for 8 seconds and an
audible attention beep goes off. To complete the dive without being reduced
to a lower MB level, all requested level stops must be observed.
To the right of the
LEVELSTOP
arrow, the deepest level stop is displayed in
metres/feet. The display "3m 2:" ("10ft 2:") means that a level stop of
2 minutes at a depth of 3 metres (10ft) has to be observed.
When a level stop obligation is finished, the next higher level stop – if
present – is displayed. When all level stops have been observed, the arrow
LEVELSTOP
extinguishes and the arrow
NO STOP
reappears. The indication of
time shows the MB no-stop time again.
