Oceanic Veo 100Nx ユーザーズマニュアル

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 Veo 100Nx automatically compensates for decreased ambient pressures for Altitudes

between 2,000 (610 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 Veo 100Nx 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 2,000 feet (610

meters), it will automatically recalibrate itself to measure depth in feet of fresh water rather

than feet of sea water.  It will then readjust  the no decompression and oxygen  limits at

additional intervals of 1,000 feet (305 meters).  Therefore, when returning to lower Alti-

tudes, 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.
