Atmospheric Pressure is the pressure at any location on earth, caused by the weight of the column of

air above it. One atmospheric pressure refers to the average pressure and gradually decreases as alti-

tude 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 measur-

ing the changes in pressure.

1. Press the BARO button to switch between barometric pressure display in inHg or in hPa.

2. Press the BARO button for 3 seconds to change between absolute and relative atmospheric pres-

sure.

• ABSOLUTE: the absolute atmospheric pressure of your location.

• RELATIVE: the relative atmospheric pressure based on the sea level.

Set relative atmospheric pressure value

3. Get the atmospheric pressure data of the sea level (it is also the relative atmospheric pressure

data of your home area) through the local weather service, internet and other channels.

4. Press and hold the BARO button for approx. 3 seconds until "abs" or "rel" flashes.

5. Press CH/UP or 12/24/DOWN button to switch to "rel" mode.

6. Press the BARO button and the number for "rel" flashes.
