21 Barometric / Atmospheric Pressure
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 enter the setting mode.
2. Press the BARO button again, to change the unit between inHg / mmHg / hPa.
3. 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
4. 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.
5. Hold the BARO button for approx. 3 seconds, until ABSOLUTE or RELATIVE flashes.
