VII Trouble Shooting
Displayed tank pres-
sure does not corres-
pond to pressure mea-
sured by a manometer
(depth gauge).
The logbook does
not show any gas mix-
ture consumption (dp)
for a certain dive.
Altitude section does
not correspond to the
current altitude.
By compensating for temperature, the
pressure displayed is valid at 20 °C.
If the gas or water temperature differ
from this value, a difference to the
value given by a manometer is pos-
sible.
Tank and transmitter do not have the
same temperature (only possible in
air).
Manometer/depth gauge is not accu-
rate (temperature 20 °C).
No tank pressure signal was received
at the beginning or end of the dive.
Transmitter and dive computer were
not paired before the dive started.
The dive has been made with an Oxy2.
Atmospheric pressure is especially
high or low.
Ambient air pressure measured by
the computer is wrong.
Make comparison at 20 °C or check
the tank pressure compensated to
the atmospheric pressure for compa-
rison (see page 98).
Leave the tank with the regulator
mounted and the gas mixture turned
on for five to ten minutes.
Measure tank pressure with another
manometer/depth gauge (at 20 °C).
Mount transmitter correctly
(see page 35).
Pair transmitter and computer
(see page 40).
Check barometric information.
Send in dive computer for servicing
(only if altitude section is wrong by
more than one section, see page 70).
