  • Page 33: Bar Graph

    BAR GRAPH The AT M features one shared Bar Graph that represents either nitrogen loading, or when accessed, oxygen accumulation. By default the Bar Graph (Fig. 25a), referred to as the Tissue Loading Bar Graph (TLBG), represents your relative no decom- pression or decompression status.
  • Page 34 Displays associated with oxygen and the 2 Bar Graph will be displayed if F 2 for any Gas (1, 2, or 3) has been set at a value other than 'Air' (e.g., a numerical value) and the Alternate screen that displays oxygen related data is accessed. When the oxygen data screen is accessed during a N RM dive, the Bar Graph will show the maximum of either per dive accumu- lated oxygen or 24 hour period accumulated oxygen.

  • Page 35: Alpha / Numeric Displays

    While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk. Within the available N RM Mode parameters that can be set (described later) are a TLBG Alarm and a Conservative Factor which if set N reduces No Decompression times allowed.

  • Page 92: Positioning Of The Atom

    POSITIONING OF THE ATOM The Transmitters (TMTs) emit low frequency signals that radiate outward in semicircular patterns that are parallel to the length dimension of the TMT. A coiled antenna inside the AT M receives the signals when it is positioned within a zone parallel to or at a 45 degree angle to the TMT as illustrated on page 92.

  • Page 93: Dive Time Remaining (Dtr)

    An interruption of the TMT Link may also occur while the AT M is in an area within 3 to 4 feet (1 meter) of a running Dive Propulsion Vehicle. The Link will be restored within 4 seconds after the Vehicle is shut off or the AT M is moved out of that area.

  • Page 94: No Decompression Dive Time Remaining (Ndc)

    No Decompression Dive Time Remaining (NDC) No Decompression Dive Time Remaining is the maximum amount of time that you can stay at your present Depth before entering a Decompression situation. It is calculated based on the amount of Nitrogen absorbed by hypothetical tissue compart- ments.

  • Page 95: Oxygen Accumulation Time Remaining (Otr)

    Oxygen Accumulation Time Remaining (OTR) When the AT M is set for Nitrox operation, xygen Accumula- tion (saturation or exposure) during a dive, or 24 hour period, appears graphically as the 2 Bar Graph (Fig. 80a) when the Alternate #2 ( 2) screen is accessed. As time remaining before reaching the xygen Exposure Limit decreases, segments are added to the 2 Bar Graph.

  • Page 96: Air Time Remaining Alarm

    Air Consumption and Depth are continuously monitored and Air Time Remaining reflects any change in circumstances. For example, when a buddy starts breathing from your ctopus or you suddenly find yourself swimming against a strong current and begin breathing more rapidly, the AT M will recognize the change and adjust the Air Time Remaining accordingly.

  • Page 97: Variable Ascent Rate

    You should immediately initiate a controlled Ascent while moni- toring your Tank Pressure. However, there is no reason to panic, the AT M has allowed for the Air necessary for a safe Ascent including the No Deco Safety Stop, if set n, and any Decompression Stops required.

  • Page 98: Elapsed Dive Time

    At 60 FT (18 M) and shallower, the Warning will be given when Ascent Rates exceed 25 FPM (7.5 MPM). Ascent Rate Alarm At depths deeper than 60 FT (18 M), an Alarm will sound when Ascent Rates exceed 60 FPM (20 MPM).
