Selecting the temperature unit °C/°F
The
°C/°F
slider (19) for the temperature unit of the display is located on the rear of the weather station. This allows
you to switch the temperature unit for the display between °C (degrees Celsius) and °F (degrees Fahrenheit).
b) Air pressure unit and air pressure display
Atmospheric pressure is the pressure at any point on the earth caused by the weight of the air column above it. An
atmospheric pressure refers to the average pressure and gradually decreases as the altitude increases. Meteorolo-
gists measure the air pressure with barometers. As the change in air pressure is heavily dependent on the weather, it
is possible to predict the weather by measuring the changes in pressure.
