USING THE NiTek Q Battery and Charge Set-up Your NiTek Q uses a rechargeable Lithium polymer battery that is sealed inside the housing. You will need to check the battery level and fully charge the battery before the first use (and afterwards, as needed). The best battery life will come from keeping the battery charged. A full charge will last for approximately 20 hours of dive time (depending on screen brightness settings).
USING THE NiTek Q SURFACE Mode The SURFACE mode is the NiTek Q’s default screen. At the surface, the computer automatically returns to this mode from any other screen after 20 seconds, (slightly longer than 20 seconds when in profile and compass modes). Upon surfacing from a dive, the computer also returns to the SURFACE mode screen, and displays additional post-dive information (see page 16).
MENUS Menus Dive Option SET and Display Mode The dive option SET and display mode is where all “dive” settings are programmed including your P02 alarm for each gas, %02, the maximum safe operating depth (MOD), an optional maximum depth alarm, a maximum dive time alarm, conservatism/gradient factor options, a sampling rate for the log book, the FRESH or SEA water option, and screen brightness control. When the computer is in this mode, “SET” is displayed in the lower left hand corner of the screen.
MENUS SET Screen Two - The NiTek Q has maximum depth and time alarms that can be set on SET Screen Two. These alarms will be activated when the diver reaches selected presets. When the maximum depth is reached, the current depth indicator will flash until you ascend to a depth that is shallower than the maximum depth you have set. The Maximum Depth alarm can be set from 0 – 492 feet (0-150 meters).
MENUS 4. 5. Press the B button to toggle through the selections. • CONS2 = 30/75 (default/most conservative) • CONS1 = 40/100 • CONS0 = 75/95 Press the A button to lock in your choice and advance to the Imperial/Metric option. To exit, press and hold the A button for 2-3 seconds to return to the Surface mode. Web Resource - Learn about setting custom gradient factors in Dive RIte’s library at: http://www.diverite.
MENUS These calculations are based on: • • One atmosphere of saltwater = 33 feet (10 meters) One atmosphere of freshwater = 34 feet (10.3 meters) To set for FRESH or SEA Water Use: 1. 2. 3. 4. 5. Press the A button until “SET” is displayed. Press the B button to enter the dive set up option screen (SET Screen One). Repeatedly press the A button until the screen scrolls through SET Screens One and Two, changes to SET Screen Three and “FRESH” or “SEA” is flashing.
MENUS Using the PLAN Mode 1. 2. 3. 4. Repeatedly press the A button until “PLAN” is displayed. Press the B button to enter the PLAN mode screen. Press the B button to advance the depth. The no-decompression time limits change automatically based on the depth. When finished, press and hold the A button return to the SURFACE mode. Do not plan dives to depths deeper than those for which the NiTek Q is capable of displaying an available no-decompression limit.
MENUS Dive profile information is either stored in 15-second or 30-second intervals during a dive. This must be set prior to making your dive. Refer to “Setting the Dive Log/Profile Sampling Rate” on page 10 for step-by-step instructions. The dive number and date of the dive are displayed when you scroll through your dives, making it easy to find the dive profile you want to view. 1. 2. 3. Dive Log number – This is the dive number that corresponds to the dive number when in LOG mode.
DIVE MODE tion about your dive and prompts you with safety stop information and warnings, if needed. When diving, there are two screens you can toggle between, and you can switch to different gas mixes, when needed.
DIVE MODE The NiTek Q does not monitor breathing gas supply. You must monitor this yourself, on every dive, using a submersible pressure gauge or equivalent device. Decompression If you exceed the no-decompression limits during a dive, the computer enters the decompression mode. This indicates that you will have to limit your ascent time and enter a series of one or more decompression stops. 1. 2. 3. 4. 5.
DIVE MODE To Change Gases Underwater 1. 2. Press the A button. The mix number will flash. Press the B button to select a mix number. The 02 percentage will change to the programmed mix and the P02 indicator will change to reflect the P02 set for the selected mix. NOTE: Only the mix numbers that have been programmed with a gas mixture are available. 3. Press the A button to lock in the mixture and return to the primary diving mode. NOTE: You cannot lock in a mix if it causes you to exceed a P02 of 1.
DIVE MODE Altitude Operation The NiTek Q adjusts automatically for diving at altitude. The Q monitors altitude information in all modes, except PC transfer mode. Upon arriving at altitude, the NiTek Q’s PGT bar graph may show that there is excess nitrogen present, even though you may not have made any dives in the preceding 24 hours.
CARE & MAINTENANCE Decompression Stop Violation Warning A decompression stop violation warning is triggered when you ascend to a shallower depth than the indicated stop depth or if you do not spend sufficient time at the required depth before ascending. If you violate the decompression obligation, the computer’s “DECO” symbol will flash and continue to flash as long as you remain shallower than the indicated stop depth.
WARRANTY & ACCESSORIES 3. 4. 5. 6. If the NiTek Q does not appear to be functioning properly, do not use it to dive. Return it to your authorized Dive Rite dealer for repair. The NiTek Q should not come in contact with solvents or any type of chemical substances. Do not use compressed air to dry the NiTek Q. Do not use the NiTek Q in hyperbaric chambers unless the device can be fully submerged in water inside the chamber during recompression.
Appendix A - TRIMIX UPGRADE Normoxic or Hypoxic Trimix Upgrade Instructions If you have upgraded to normoxic or hypoxic Trimix, you will be programming your computer for a percentage of helium as well as oxygen. The SURFACE mode, DIVE mode, PLAN mode, and LOG mode screens reflect the additional gas option in your mix choices. You will need to become familiar with and learn how to manage the addition of helium to your breathing gas throughout these menus.
Appendix A - TRIMIX UPGRADE 5. 6. 7. 8. Press the B button to select your %02 for this mix. Press the A button to lock in your %02 and the computer will automatically advance to your %HE. Press the B button to select your %HE for this mix. Press the A button to lock in your %HE and the computer will automatically advance SET screen two. To exit, press and hold the A button for 2-3 seconds to return to the Surface mode.
Appendix A - TRIMIX UPGRADE DIVE Mode The DIVE computer mode is automatically entered when the computer enters the water. It begins performing its dive calculations once you descend below 5 feet (1.5m). While in DIVE mode, the computer calculates and displays information about your dive and prompts you with safety stop information and warnings, if needed. When diving, there are two screens you can toggle between, and you can switch to different gas mixes, when needed.
Appendix A - TRIMIX UPGRADE LOG Mode The NiTek Q stores information, such as depth, time, and gases, for every dive in a log. This stored information can be viewed on screen in the LOG mode. The logbook holds a minimum of 15 hours, depending on settings. Each dive is assigned a log number and the date the dive is made, making it easy for you to toggle between the dive log pages. 1. 2. 3. 4. 5. 6. Log Entry Number – This is the sequence in which the log appears.
Appendix B - CCR UPGRADE CCR Upgrade Instructions If you have upgraded to CCR for your NiTek Q, your computer can now be used with closed circuit rebreathers using a constant–P02 setpoint ranging from 0.4 to 1.6. The CCR upgrade allows you to program the NiTek Q with the set point you have programmed into your rebreather. As long as you run the rebreather at the setpoint you programmed into the Q, it will provide accurate dive and decompression information.
Appendix B - CCR UPGRADE Your maximum operating depth (MOD) is also displayed on SET Screen One. The MOD is the safe operating depth (maximum) for the mix selected and will automatically update to reflect the chosen P02 limit (either 1.4 or 1.6) To Set P02 Setpoints NOTE: If you only plan on using one P02 setpoint and mixture on your dive, you only need to set that P02 and mix. From the SURFACE mode screen, repeatedly press the A button to reach the SET screen. 1. 2. 3. 4. 5. 6.
Appendix C - CUSTOM GF UPGRADE Custom Gradient Factor (GF) Upgrade Instructions Your custom gradient factor upgrade allows you to set your own gradient factors. The NiTek Q automatically defaults to the most conservative gradient factor setting. Creating and using custom gradient factors should only be undertaken by those who understand the consequences of these settings. Aggressive settings should not be undertaken lightly. It is not recommended diving any computer to the maximum limits.
Appendix D - COMPASS UPGRADE COMPASS Upgrade Instructions Now that you have added a digital compass to your computer, it must calibrated before use. When the DIVE mode is activated when you enter the water, the compass is displayed on the second underwater screen. COMPASS Mode Screen To Calibrate Your Digital Compass From the SURFACE mode screen repeatedly press the A button to scroll to the COMPASS screen. 1. Press and hold the B button while holding the computer in a horizontal position.
