7. GENERAL OPERATION AND FUNCTIONS:

7.1 Barometer:

The atmospheric pressure value is measured with a barometer. The
atmospheric pressure value can be displayed in Ft, M, inHG, and hPa.
In the Benelux, the hectoPascal notation is used; although previously
air pressure was also expressed as 1 mbar equals 1 hPa. The
atmospheric pressure decreases the higher you are above sea level. A
rule of thumb is that the atmospheric pressure decreases by 1 hPa per
8 meters. In this weather station menu, the height can be entered so
that the air pressure is compensated for and the correct air pressure
value is displayed. The height can be adjusted in 10-meter increments
between -90 meters and +1990 meters. See 6.4 for this setting.

If the atmospheric pressure increases or
decreases by 2 hPa per hour, the trend
display will point up or down. If the air
pressure changes less than 2 hPa per
hour, the straight arrow will be displayed.
