No reception of tank
pressure data.
Bad reception of tank
pressure data.
Displayed tank pressure
does not correspond
to pressure measured
by a manometer (pres-
sure gauge).
Transmitter and computer are not
tuned to each other (paired).
Transmitter or receiver in the compu-
ter are defective.
In surface mode if there is no decrea-
se in pressure for 3 minutes the pres-
sure data will not display.
Transmitter is not mounted correctly.
Transmitter, or receiver in the compu-
ter are defective.
By compensating the temperature,
the pressure displayed is valid at
20 °C.
If air- or water-temperature differ
from this value, a difference to the
value given by a pressure gauge is
possible.
Tank and transmitter do not have the
same temperature (only possible in air).
Manometer/pressure gauge is not
accurate (temperature 20 °C).
Pair transmitter and computer
(see chapter II 4).
If the pairing is not possible with ano-
ther transmitter, the receiver in the
computer is defective. Have transmit-
ter or dive computer repaired.
Change the pressure by breathing
from the regulator. Tank data will re-
appear.
Mount transmitter correctly
(see chapter II 4)
If the pairing is not possible with ano-
ther transmitter, the receiver in the
computer is defective. Have transmit-
ter or dive computer repaired.
Make comparison at 20 °C or check
the tank pressure compensated to
the atmospheric pressure for com-
parison (see appendix, chapter IX).
Leave the tank with the regulator
mounted in the open air for 5 -10
minutes.
Measure tank pressure with another
manometer/pressure gauge (at 20 °C).
