What type of information do dive computers display?

Air integration feature allows the diver to measure tank pressure and calculate how much time has left before having to finish the dive. For more information, check out this website: http://divecomputer.com.au/types-of-dive-computers/

Dive computers are computer devices that allow a diver to measure both the time under water and the depth level he has reached. This allows the diver to avoid having DCS, or decompression sickness.

This watch needs to be sent back to the factory to get the movement replaced. I am doing this for the second time in 4 years. Citizen Europe states it's a defective design. The watch goes into dive mode with sweat, humidity and washing your hands. The water sensor tells the computer it's gone diving but the pressure sensor isn't telling it the same thing which causes a fault with the computer. I was told to cover the water sensor with WAX by the factory repair facility. WAX on a $400 dive watch. Great. They shold have used the pressure sensor to initiate dive mode. Customer Service said it wasn't defective, so it was designed to need this part everytime the battery has to bre replace.

All dive computers will automatically come off dive mode when they are out of water. sounds like you may have water in it. I strongly recommend that you do not dive with this unit but send/take back to the place where you got it. I would guess it is still under warranty. Hope that helps

When the amount of available memory in flash memorybecomes low, "FILE" flashes in the lower left corner ofthe display in all of the submodes of the standard mode as well as in the dive mode. Thewatch automatically switches to the flash memory statusdisplay of the system monitor mode when the water sensor gets wet while thiswarning function is activated. Please note that although it is possibleto use the watch for diving in this state, log data may not be recorded inflash memory during diving. The file error warning function is also activated andadditional log data is not recorded if the duration of a single dive exceeds 2 hours or if morethan 15 dives are made in a single day. The file error warning function may also be activated whenthe water temperature during diving is low. It may not be possible to receive watchsettings by data communication while the file error warning When the watch has switched to the file error warningdisplay, perform the garbage collection procedure in the system monitor mode of the standardmode. Thedisplay returns to normal following completion of garbagecollection. Garbage collection begins when button (C) is pressedfor at least 2 seconds during the flash memory status display. • During the garbage collection operation, an alarmsounds and "G.C." is displayed on the display. When garbage collection is completed,"Done" is displayed on the display. • Garbage collection cannot be performed when"G.C." has changed to "NG" on the battery charge indicator or when the water sensor hasbeen activated. "Fail" is displayed on the disPress button (B) in the system monitor modeof the standard mode to switch the watch to the Flash Memory Status Display. Formatting Flash Memory Formatting of flash memory begins when button (B) is pressed while pressing button (C) simultaneously forat least 2 seconds.play at this time. [email protected]

Hi,

Please check the manual if it helps:-

Please accept the solution if it's helpful. Do get back to us for any further query.

Do you live somewhere significantly above sea level?

If not, check your personal altitude setting. It's explained on pages 20 and 23 of the manual.

Scuba gauges give a diver three very important pieces of information: 1. Time 2. Depth 3. Air Consumption This information enables a diver to stay within safe time and depth limits and avoid running out of air. There are many different devices on the market to help with this, from simple gauges to complex digital consoles. Time If a diver is not using a dive computer to monitor their nitrogen, they dive according to approved dive tables. To use dive tables properly, a diver needs to track their downtime. This can be done with a good dive watch. Two things make a good dive watch: water resistance and a rotating bezel. 1. Water Resistance. Good dive watches are rated to a depth in meters or feet (e.g. 200 feet) or a pressure rating in atmospheres (e.g. 4atm). Even though most divers probably won’t dive below 130 feet (the recreational dive limit), a good dive watch should be rated to 200 feet. Note: There is a difference between “water resistance” and “waterproof”. A “waterproof” watch is what you would wear in the shower, but would probably start leaking at 15-20 feet. 2. Rotating Bezel. A bezel is an adjustable ring on the face of the dive watch with a pointer indicator. At the beginning of a dive, the pointer on the bezel is aligned with the minute hand where it stays though out the dive. At the end of the dive, you compare the difference between the bezel and the minute hand to find out the length of the dive. The bezel should only move “counterclockwise”. It is possible to accidently move the bezel during a dive. Because of this, watchmakers make sure any accidental movement will turn the time in a conservative direction, making the dive longer rather than shorter. Depth Another important part of scuba gauges is a depth gauge. A depth gauge enables a diver to keep track of their depth even if they cannot see the water’s surface. Gauges can be either an analog (needle-and-dial) device or a digital device. Both work in the same way. They measure the surrounding water pressure and convert this into an accurate reading of your depth. Another feature of a good depth gauge is a maximum depth indicator. This tells a diver their maximum during a dive and must be reset after each dive. Air Consumption Another equally important part of scuba gauges is a submersible pressure gauge (SPG). This is connected to the first stage with a high-pressure hose and measures the pressure of the air in the tank. The SPG is much like the gas gauge on a car. At the beginning of a dive, a diver starts with a full tank. This should be about 3000 psi or 200 bars. As the diver breathes during the dive, the gauge will move slowly downwards. This allows the diver to have enough air left in the tank to: 1. Make a slow, safe ascent 2. Make any necessary decompression stops 3. Inflate their BCD once at the surface 4. Breath from the regulator if the surface conditions are rough A submersible pressure gauge also allows a diver to stop diving with air still in the tank. This keeps contaminants from entering the tank due to no air pressure. Wrist Depth Gauge Scuba gauges come in two basic styles. Stand alone gauges or gauge consoles. Stand alone gauges such as a wrist mounted depth gauge or a submersible pressure gauge attached to the first stage of a regulator are great backups when using digital gauges. Gauge consoles allow divers to have all their gauges in one place. Although less easy to read, analog gauges sometimes give slightly more accurate readings than digital gauges, particularly at shallow depth. Submersible Pressure Gauge Choosing Scuba Gauges When choosing scuba gauges, remember to look for: 1. Easy-to-read numbers 2. Luminescent dial or back lighting options 3. Rotating/swivel mounting 4. Easy disassembly for cleaning or replacing parts 5. Good warranty
