be completed to a complete SCUBA with components, which passed the EU-Certification and come up to
the EN 250 norm.
According to the EN 250 a complete SCUBA consists at least of the following components:
a) Air pressure tank(s) and tank valve(s)
b) Regulator
c) Safety equipment
d) Frame or holding device for air cylinder(s) with the possibility to mount the harness
e) Carrier device
f) Breathing connection (face mask and mouthpiece, full face mask, or diving helmet)
g) Instructions for use must be included
The high-pressure hose of the Digital Pressure Gauge is equipped at its connection (7/16“) with a flow
through reduction.
According the law of technical working devises we point to the following points:
• Base of each use of the Digital Pressure Gauge and its component parts is the knowledge and consideration of this Manual.
• The Digital Pressure Gauge may only be used for the purposes mentioned in this manual or confirmed in
writing by Uwatec.
• The Digital Pressure Gauge has to be yearly inspected (inspection-maintenance-reparation) by an educated authorised person. These inspections have to be recorded. Only original Uwatec spare parts may be
used for replacements.
• The EN 250 Certification maximum depth is 50 m.

Introduction / Overview
Symbols: Logbook, Set Up, Maintenance, Battery warning
Contact E
Contact S
The Uwatec Digital Pressure Gauge measures the tank pressure and displays
it together with the ambient temperature on the display. A high-pressure
hose connects the Digital Pressure Gauge on the first stage of the diving tank.
The Digital Pressure Gauge has two pressure alarm values. One is fixed at 50
bar, the other one can be set by the user between 30 and 100 bar (450-1500
psi). The Digital Pressure Gauge warns the diver optically and acoustically if
the tank pressure falls short off one of these pressure alarm values.
Furthermore the diver can select the units for the pressure and temperature
indication.
The logbook stores the original and the final tank pressure of a given dive and
displays the pressure difference.

Safety considerations / Warnings
Do not use the Digital Pressure Gauge, until you have carefully read all
instructions and safety precautions found in this manual.
Diving has many inherent risks. Even if you follow the instructions of this
manual, it is still possible that you may not have enough air until the end of
the dive. Unless you are fully aware of the risks and are willing to personally
accept responsibility for those risks, do not use the Digital Pressure Gauge!
• The Digital Pressure Gauge may only be used together with compressed air.
Do not use it for oxygen enriched gases.
• The Digital Pressure Gauge does not give any warning about a too low air
reserve. Check frequently your tank pressure!
• Do not use on cylinders charged above the maximum working pressure. See
"Technical Information" page 23.
• The Pressure Gauge may only be used if it is in working condition.
• If your diving cylinder is equipped with a reserve or „J“-type valve, make certain that the reserve function is in an open position for the Digital Pressure
Gauge works correctly.
• Rubber boot and console must not cover the overpressure valve, enabling air
to leave without resistance. (Hole diameter 6 mm)

Safety considerations / Warnings
• There is a danger of insufficient air supply if air leaves the over pressure valve
or another part of the measurement system. Start ascent immediately!
• The Pressure Gauge should be secured in a way that will not cause the unit
to be caught or snagged whilst diving.
• If the maintenance symbol appears, do not continue diving with the
Digital Pressure Gauge anymore. If the symbol appears during a dive: start
ascending immediately! If the maintenance symbol appears, the display may
be blocked without further warning. Take the unit to your authorised Uwatec
Dealer for battery exchange.
• If „CAL“ appears, you must not dive with the Digital Pressure Gauge any
more. If the symbol appears during a dive: start ascending immediately! The
display is blocked. Have the unit repaired.
• If the Digital Pressure Gauge fails at any time during the dive, the dive must
be terminated except when a second pressure gauge is available.
• Retain this manual for your reference.
• The Digital Pressure Gauge has been exclusively made for sports diving (EN
250). It may only be used together with high-pressure hose with a flow
through reduction.

Set Up Procedure
Switching the unit on and off
The Digital Pressure Gauge can be switched on either by bridging the contacts
B and E or if the connected tank pressure exceeds 8 bar.
After switching the unit on by bridging the contacts the display shows for a
short time all segments and goes into the User Mode, which can be run
through by bridging B and S as many times you want. See „User Mode“,
page 10.
P > 8 bar
If the pressure (>8 bar) switches the unit on, it will switch directly into the
Measurement Mode (see page 17).
The unit switches off automatically after 3 minutes if no entry has been made
and the pressure is less than 8 bar. See also „Overview user interface“, page 26.
