Adjusting the air pressure indication
The forecast of this weather station is basing on an analysis of the change of the
air pressure.
The barometric pressure
As the air pressure generally decreases with the height beyond sea level, the public
weather service always announces the so-called relative air pressure. This relative
air pressure is adjusted to the topography of the country in order to get comparable
values.
You can adjust the air-pressure of your weather station to the proportion of its place.
For that you have to adjust your weather station uniquely the current air pressure.
Ask your local weather forecast service for the barometric pressure at sea level or
get the current value from the Internet.
You can adjust the weather station like this:
Press and hold the HISTORY ABS / REL button
that press the + or – button
relative air pressure.

pressure indication blinks. Now you can chose the correct value by pressing

Confirm your choice by pressing the HISTORY ABS / REL button. Your weather
station now shows the relative air pressure.
