1. - INTRODUCTION.
Congratulations on your purchase of your , underwater
computer, a sophisticated and complete instrument, realized
in order to offer you the utmost performance, reliability
and safety.
1.1. - Main specifications.
• The Bühlmann ZH-L12 algorithm has been refined by
Randy Böhrer, in order to make available a more sophisti-
cated RGBM program. The result is an algorithm very simi-
lar to ZH-L16, though less penalizing as to the water tem-
perature and the repeated exceeding ascent rate;
• Tissues: 12, with saturation hemi-phases between 5 and
640 minutes;
• DIVE PROGRAM:
Dive data full processing - with possible decompression as
well - of any air or hyper-oxygenated mixture (Nitrox) dive
• Full setting of Nitrox parameters (FO2 and PO2): PO2 may
be set between 1.0 bar and 1.6 bar, while FO2 between
21% and 50%
• A Nitrox dive may be carried out after an air dive (even by de-
saturation in progress)
•
GAGE (or depth gauge/timer) PROGRAM may be set
•
FAEE (apnoea) PROGRAM may be set
• system display for a perfect understanding and
readability of values
• Manual dive planning (scrolling)
• Unit of measure changing from the metric system (meters
and °C) to the feet system (ft- °F) by the user
• Sound and visual alarm systems
• Nitrogen saturation graphic indicator
• CNS oxygen toxicity graphic indicator
• Back-luminescent display
• Incorporated calendar and clock with alarm and time zone
functions
• Logbook (30 hours or last 60 dives) including dive profile
• Dive historic memory
• The instrument may be fully reset, in case of renting
• PC interface (accessory)
