Uwatec® Digital Pressure Gauge 5 Introduction / Overview 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.

Uwatec® Digital Pressure Gauge 9 English Set Up Procedure Before the first dive Before the first dive the value of the tank pressure alarm and the units for the pressure and temperature indication has to be set. Without new settings the default settings will be valid. User Mode / The User Mode allows to... · read the logbook (pressure difference, pressure at the beginning and at the end of a dive). See page 19. · set the value of the user selectable tank pressure alarm. Setting can be made between 30 and 100 bar (450-1500 psi) in steps of 10 bar (150 psi). See page 11. · select the unit of the pressure and temperature indication. See page 13. On page 26 and 27 a graphical overview of the user interface is shown. If the display is switched off, bridge B and E to enter into the User Mode. If the unit indicates the tank pressure (Measurement Mode), the pressure has to be reduced below 8 bar (120 psi) to enter into the User Mode. The User Mode will be left automatically after 3 minutes (switching off) or if the tank pressure exceeds 8 bar (120 psi). 10 Uwatec® Digital Pressure Gauge Set Up Procedure The User Mode is programmed as a loop, which can be run through by bridging B and S, as many times you want. See also overview user interface, page 26. If the User Mode is left during the setting of the tank pressure alarm or the units, the indicated value will not been taken in to account, the old setting will be kept. Set up the tank pressure alarm Independent of the fixed 50 bar (750 psi) pressure alarm you can enter your own tank pressure alarm value. See also page 6 and 18. The Digital Pressure Gauge has to be in the User Mode (see page 10). Bridge the contacts B and S until the symbols for the Set Up and the tank pressure alarm are indicated. The Digital Pressure Gauge displays the actually set value of the tank pressure alarm. The default value of the user selectable tank pressure alarm is 50 bar (750 psi). If you don`t want to change the indicated valve, bridge the contacts B and S. If you want to change the indicated value, bridge B and E. The value of the tank pressure alarm starts flashing. until Uwatec® Digital Pressure Gauge 11 English Set Up Procedure · The value of the tank pressure alarm should not be selected lower than 50 bar. Lower values should only be selected if special precautions have been taken. · If a low value of the tank pressure alarm has been selected, the alarm may be activated to late. Serious injury or death from not having enough air may occur. Select the value of the tank pressure alarm high enough! Overview set up tank pressure alarm Each bridging of the contacts B and S increases the value of the tank pressure alarm by 10 bar (150 psi). When the pressure alarm setting reaches 100 bar (1500 psi) the next contact of B, S will loop the alarm setting to 30 bar (450 psi). Bridging the contacts B and E confirms the actual displayed value as the new tank pressure alarm and the displayed alarm value stops flashing. If the measured pressure falls short of this value, the Digital Pressure Gauge activates the tank pressure alarm. 12 Uwatec® Digital Pressure Gauge Set Up Procedure Set Up pressure and temperature unit until The Digital Pressure Gauge has to be in the User Mode (see page 10). Bridge the contacts B and S until the symbol for the Set Up Mode and both the pressure and temperature units appear. English The Digital Pressure Gauge shows the actual combination of pressure and temperature units. If you don`t want to change the displayed units, bridge the contacts B and S. Overview units To change one or both units, bridge B and E. The displayed units start flashing. The display shows the next combination of units after bridging the contacts B and S. Bridge these contacts until the display shows the units of your choice. Bridging B and E confirms the displayed units as the new combination. The displayed units stop flashing. Uwatec® Digital Pressure Gauge 13 Set Up Procedure Mounting the high-pressure hose to the first stage Adaptor The high-pressure hose is mounted on the high-pressure outlet (HP-outlet) of the first stage of the regulator. 1. Mount the high-pressure hose on the HP-outlet. If the threads do not match, you can obtain an adapter from your diving retailer. HP 2. Tighten the connection with a matching wrench. Connecting the Digital Pressure Gauge Make sure that the tank valve is closed and the regulator is depressurised. 1. Place the bayonet ring of the high-pressure hose on the connecting part of the Digital Pressure Gauge in such a manner that the guiding pins of the bayonet ring grip into the guides provided. 14 Uwatec® Digital Pressure Gauge Set Up Procedure 2. Turn the bayonet ring to the right until it reaches the stop and then let go of the ring. Make sure that the bayonet ring springs back a few millimeters. Check the correctness of the connection by forcefully pressing and pulling the hose. The bayonet ring must have a range of spring of a few millimeters. 3. Open the tank valve and check the tightness of the connections. Check tank pressure before every dive. If the pressure exceeds 8 bar the Digital Pressure Gauge switches automatically to the Measurement Mode (see page 17). Uwatec® Digital Pressure Gauge 15 English Set Up Procedure Disconnecting the Digital Pressure Gauge After diving, the Digital Pressure Gauge can be disconnected. Make sure that the tank valve is closed and the regulator is depressurised. The Digital Pressure Gauge cannot be disconnected under pressure. Never try to disconnect the Digital Pressure Gauge under pressure. 16 Uwatec® Digital Pressure Gauge Measurement Mode In the Measurement Mode the Digital Pressure Gauge indicates the tank pressure (numerically and graphically) and the temperature. The Digital Pressure Gauge activates an optical and acoustical alarm if the tank pressure goes below the fixed 50 bar alarm or below the user selected alarm pressure value. English Independent of the actual mode of the Digital Pressure Gauge, it activates the Measurement Mode as soon the connected pressure exceeds 8 bar (120 psi). P > 8 bar P < 8 bar If the pressure falls short of 8 bar (120 psi), the unit switches to the User Mode. Measurement Mode The number of bars shown in the tank symbol correlates to the relation between the actual pressure and 200 respectively 300 bar, depending on the measured maximum pressure. If the maximum pressure exceeds 250 bar (3600 psi) the number of bars is displayed as a proportion of 300 bar (4500 psi). With a maximum pressure of less than 250 bar (3600 psi) the number of bars is proportional to 200 bar (3000 psi). Uwatec® Digital Pressure Gauge 17 Tank Pressure Alarm , In the Measurement Mode the unit alarms the diver if the pressure falls short of the set value of the tank pressure alarm or 50 bar (750 psi). The alarms, given acoustically and graphically, warn about the danger of not having enough air until the end of the dive. The alarms are given on the surface and under water. If the pressure falls short of the set value of the tank pressure alarm or 50 bar (750 psi) the symbol gets indicated and an acoustic alarm signal is given. If the pressure falls under the selected value of the tank pressure alarm, the unit repeats after every 5 bar (50 psi) pressure reduction the acoustical alarm signal. · Start ascending immediately if an optical or acoustical tank pressure alarm is given. · Even if the Digital Pressure Gauge gives no tank pressure alarm, the air reserve can be used up before the end of the dive. Frequently check the tank pressure and start ascending early enough. · If you don`t start ascending after a tank pressure alarm, you may not have enough air until the end of the dive. · If the pressure is less than 8 bar, there is no warning given by the Digital Pressure Gauge. 18 Uwatec® Digital Pressure Gauge Preparation for the Dive Make sure before each dive that the · Digital Pressure Gauge is correctly mounted (see page 14) · selected value of the tank pressure alarm is high enough (see page 11) · If the air reserve is to low for your dive, it may result in serious injury or death. Check the tank pressure before each dive. · Never dive with leaky equipment! Check the connections and the instruments against leaking parts. Logbook The logbook stores the tank pressure at the beginning and the end of the last dive and displays the pressure difference. The Digital Pressure Gauge has to be in the User Mode (see page 10). Bridge the contacts B and S until the Logbook symbol appears. Pressure difference: Beginning/end Uwatec® Digital Pressure Gauge 19 English Logbook If the tank pressure exceeds 8 bar, the unit switches to the Measurement Mode. After 3 minutes in the Logbook Mode, it switches off automatically. Pressure at the beginning The User Mode is programmed as a loop that can be run through by bridging B and S, as many times you want. See overview user interface page 26.
