    The MOD is a function of ppO max and the mixture used. If during the dive the MOD is reached or exceeded XP-H sends an audible attention message and the MOD is displayed (flashing) in the lower left corner. Ascend to a depth shallower than the displayed MOD in order to diminish the danger of oxygen poisoning.

  • Page 24: Nitrogen Loading Bar Graph

    Functions during the dive 4.8 Nitrogen loading bar graph The nitrogen loading bar gives a graphical representation of how close to decompression you are. As you absorb nitrogen during the dive, more and more segments of the bar will light up. Depending on your depth, the segments can light up more or less rapidly.

    (level stop) sooner than a diver using level L0. If a diver ignores a required level stop, XP-H will cascade to a lower MB level and the dive can not be completed with the initially chosen MB level. E.g. if a diver sets level L4 on XP-H prior to the dive and during the dive ignores the recommended stops XP-H will automatically adjust the setting to level L3 or lower.

  • Page 32: Comparison Of Dives With Mb Level L0 And Mb Level L5

    8.1 Comparison of dives with MB level L0 and MB level L5 When two XP-H are used simultaneously, one unit is set for example to MB level L5, the other to L0, the no-stop time will be shortened and level stops will be required before the diver has the obligation of a decompression stop.

  • Page 35 The warning “MB level reduced” is activated if the diver ascends more than 1.5m (5ft) above the required level stop. XP-H reduces the MB level, an attention beep* goes off and the new MB level is shown in the lower left corner.

WARNING Avoid decompression dives when diving with MB levels. How to avoid decompression stops:...

  • Page 37: Complete A Dive With Mb Levels

    Repetitive dives and MB levels: If during a dive a level stop is being ignored and the diver starts another descent shortly afterwards, XP-H might immediately request level stops. To complete the dive with the initially set MB level all level stops must be observed.

  • Page 38: Pdis (Profile Dependent Intermediate Stop)

    Spending 2 or 15 minutes at 30m/100ft would result in the same deep stop of 15m/50ft. With PDIS, as the name suggests, XP-H interprets your dive profile and suggests an intermediate stop that is a function of your nitrogen uptake so far. The PDI stop will therefore change through the course of the dive to reflect the continuosly changing situation in your body.

  • Page 39: How Does Pdis Work

    PDIS (Profile DependENT Intermediate Stop) 9.2 How does PDIS work? The mathematical decompression model in XP-H, called ZH-L8 ADT MB, tracks your decompression status by dividing your body into 8 so-called compartments and mathematically following the uptake and release of nitrogen in each with the appropriate laws of physics. The various compartments simulate parts of your body such as central nervous system, muscles, bones, skin and so on.

    NO to indicate the fact that you have not performed the PDI stop. If XP-H is displaying a decompression obligation when you reach the PDIS depth during an ascent, all rules apply the same way, but the 2-minute countdown runs in the background and is not displayed...
  • Page 41 PDIS (Profile DependENT Intermediate Stop) NOTE: XP-H issues no warnings relating to a missed PDI stop. When diving with MB levels, PDIS follows the same rules as described above. MB levels, however, introduce stops earlier and deeper than the L0 base algorithm. As such, the PDIS display may be delayed and for certain dives it may not be displayed at all.
