Diving with XP AIR
4 Functions during the dive
4.1 Immersion
After immersion, starting at a depth of about 0.8 m (3 ft), all diving functions are monitored, i.e. depth
and dive time displayed, maximum depth stored, saturation of tissues calculated, no-stop time or
decompression prognosis determined, ascent rate controlled and displayed and the correctness of the
decompression procedure supervised. In addition, XP AIR also shows the tank pressure and about 2
minutes into the dive the Remaining Bottom Time (RBT) is displayed.
4.2 Dive time
The whole time spent below a depth of 0.8m (3 feet) is displayed as dive
time in minutes. The time above 0.8m (3 feet) is counted as dive time only
if the diver descends again below 0.8m (3 feet) within 5 minutes.
While the dive time is running, the colons on the right of the figures are
flashing in one second intervals. Maximum dive time displayed is 199
minutes.
F
If a dive lasts longer than 199 minutes the dive time display starts
again at 0 minutes.
4.3 Current depth
Current depth is given in 10 cm increments (1 foot). At a diving
depth of less than 0.8 m (3 ft) the display shows "– – –".
F
Depth measurement is based on freshwater. Therefore,
XP AIR shows a slightly greater depth when diving in salt
water, depending on the salinity of the water. No calcula-
tion however is affected.
4.4 Maximum depth
Maximum depth is only displayed if it exceeds the current depth by more
than 1 m (3 feet) (maximum indicator function).

WARNING
set maximum depth reached
If the maximum depth set with Dive.Log has been reached (default
40m/130 feet), the current depth will flash and the ascent arrow will be
displayed. Ascend until the ascent arrow disappears.
