ALTITUDE COMPENSATION
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems
and ambient temperature also affect barometric pressures. Consequently, depth reading
instruments that do not compensate for the decrease in ambient pressure indicate depth
readings shallower than the depth they are actually at.
The Element automatically compensates for decreased ambient pressures for Altitudes
between 3,001 feet (916 meters) and 14,000 feet (4,270 meters). Its program contains a
high altitude algorithm that reduces no decompression and oxygen exposure limits to add
a larger zone of caution.
The Element
senses ambient pressure when it is activated, every 15 minutes while it is
activated, or every 30 minutes when it is not activated. At an Altitude of 3,001 feet (916
meters ), it will automatically recalibrate itself to measure depth in meters (feet) of fresh
water rather than feet (meters) of sea water. It will then readjust the no decompression
and oxygen limits at additional intervals of 1,000 feet (305 meters). When returning to
lower Altitudes, diving should not be conducted until the unit automatically clears of any
residual nitrogen and oxygen loading and resets to operate at the new lower Altitude.
WARNING: The Element will not sense ambient pressures or provide Altitude
compensation when it is wet. DO NOT dive at any different Altitude until the
unit shuts off and is reactivated at the new Altitude.
If the unit is activated at elevations higher than 14,000 feet (4,270 meters), it
will perform a diagnostic check followed by immediate shutdown.
