ALTITUDE SENSING AND ADJUSTMENT
Prior to the first dive of a series of repetitive dives, Altitude (i.e., Ambient Pressure)
is measured upon activation of Free Surface Mode and every 15 minutes until a
dive is made or operation reverts to Main Time after 2 hours.
> While it is operating in Watch Modes after a dive, measurements are taken
every 15 minutes during the 24 hour period after surfacing.
> Measurements are only taken when the unit is dry.
> Two readings are taken, the second reading 5 seconds after the first. The
readings must be within 1 foot (30 cm) of each other to record that Ambient
Pressure as the current Altitude.
When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270
meters), the F10 automatically adjusts to these conditions providing corrected
Depth indication at intervals of 1,000 feet (305 meters).
No adjustments are made during any time that the Wet Contacts are bridged.
At an elevation of 3,001 feet (916 meters), Depth Calibration automatically
changes from feet of seawater to feet of fresh water.
The F10 will not function as a Dive Gauge above 14,000 feet (4,270 meters).
