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 greatly
affected by weather, it is possible to forecast the weather by measuring
the changes in pressure.
Baro pressure reading
In normal mode, press [ BARO ] key to switch between ABSOLUTE / RELATIVE barometric pressure.
To set up the relative pressure:
1. Press and hold [ BARO ] key for 2 seconds to enter relative pressure setting mode.
2. Press [ WIND / + ] or [ NDX / - ] key to set the value
