    The programs within the OC1 simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The OC1 dive computer model is based upon the latest research and experiments in decompression theory.

    Link Interruption Underwater During a dive, you may at times move the OC1 out of the signal pattern of the TMT, result- ing in a temporary loss of the Link signal. The Link will be restored within 4 seconds after the OC1 is moved back into its correct position.

  • Page 80: Wet Activation

    The contacts are the metal pins of the PC Interface Data Port and the metal housing. When Wet Activation is set Off, the OC1 will not enter Dive Mode while in Watch Mode unless a dive has already been conducted and it is a repetitive dive.

  • Page 81: Bar Graphs

    BAR GRAPHS The OC1 features 2 bar graphs, one on each side of the LCD. > The one on the left is dual function. It represents either Nitrogen loading or Oxygen accumulation. The icons NI and O2 identify which is displayed at that time.

  • Page 82: O2Bg

    Fig. 67 - NO DECO ALT The OC1 will store O2 calculations for up to 10 dives conducted during a 24 hour period. If the limit for O2 is reached (100% = 300 OTU), all 5 segments of the O2BG will be displayed on the Main dive screen in place of the TLBG (Fig.

  • Page 83: Vari

    VARI The VARI (Fig. 69a) provides a visual representation of ascent speed (i.e., an ascent speedometer). The segments represent two sets of speeds which change at a reference depth of 60 FT (18 M). Refer to the chart. When ascent is too fast, all segments will be displayed flashing (Fig.

  • Page 84: Algorithm (Ndl Basis)

    You can select DSAT or PZ+ as the NDL Basis. The selection will lock in for 24 hours after the last dive. DSAT has been the standard used by Oceanic in all of its dive computers until this time. It features NDLs that are based on exposures and test data which also formed validation for the PADI RDP.

  • Page 85: Conservative Factor

    CONSERVATIVE FACTOR (CF) When the CF is set On, the NDLs which are based on the algorithm selected and used for Ni/O2 calculations and displays relating to Plan and DTR, will be reduced to the values available at the altitude level that is 3,000 feet (915 meters) higher. Refer to the NDL charts on pages 170 and 171.

  • Page 86: Safety Stop

    SAFETY STOP (SS) Upon ascending to 5 FT (1.5 M) below the SS Depth set on any NORM No Deco dive in which Depth exceeded 30 FT (9 M), the Audible will sound and a SS at the Depth set will be displayed with a countdown beginning at the Safety Stop Time set and counting down to 0:00 (min:sec).

  • Page 87: Fo2 Set For Air

    24 hours elapse after the last dive, or the FO2 50% Default is set Off. When the FO2 50% Default is set Off, the OC1 will remain set at the last FO2 Gas 1 Set Point for that period of activation.

  • Page 88: Dive Time Remaining (Dtr)

    Default is set On, all FO2 values default to 50%. • The OC1 is programmed to prevent FO2 Gas 2 and 3 from being set at values lower than the FO2 Set Point for Gas 1. Gas 2 and Gas 3 require Set Points equal to/ higher than Gas 1 and Gas 2, respectively.

  • Page 89: O2 Dtr (Otr)

    DTR on the Main. Air Time Remaining (ATR) The OC1 calculates ATR using a patented algorithm that is based on a diver's individual Air Consumption Rate and Current Depth. Tank Pressure is measured once each second and an average rate of Consumption is calculated over a 90 second period.
  • Page 90 ATR becomes greater than 5 minutes. You should initiate a controlled Ascent while monitoring Tank Pressure. However, there is no reason to panic, the OC1 has allowed for the Air necessary for a safe Ascent including the No Deco Deep and Safety Stops, if set On, and any Deco Stops required.

  • Page 91: Error (Reset During Dive)

    ERROR (RESET DURING A DIVE) If for any reason, the OC1 shuts Off then turns On again during any Dive, the graphic ERR (Error) will be displayed with the Up Arrow icon and current Depth with FT (or M) icon (Fig. 75A).
