Barometric Pressure
The atmospheric pressure is the pressure at any location
of the earth caused by the weight of the column of air
above it. One atmospheric pressure refers to the average
pressure and gradually decreases as altitude increases.
Meteorologists use barometers to measure atmospheric
pressure. Since variation in atmospheric pressure is
greatly affected by weather, it is possible to forecast
the weather by measuring the changes in pressure.
Setting the Barometer Unit: In Normal Mode,
press BARO UNIT to change the barometer unit
in this sequence: hPa inHg mmHg
Setting Relative Atmospheric Pressure Value:
1. Get the atmosphere pressure data of sea
level (or the relative atmosphere pressure
data of your home area) through your local
weather service, internet or other sources.
2. Press and hold BARO for 2 seconds
until ABS or REL icon flashes.
3. Press up or down to switch to RELATIVE mode.
4. Press BARO once again until the RELATIVE
atmosphere pressure digit flashes.
5. Press or to change the value.
6. Press BARO to save and exit the setting mode.
