Your weather station displays the existing atmospheric pressure in inHg (inches of mercury) and
hectopascal (hPa).
Barometric pressure historical graph
The bar graph lets you see the pressure trend over the past 30 hours.
Barometric pressure trend
The trend pointer displayed indicates the trend of the barometric pressure. Generally, bad weather
is associated with low pressure and fine weather with high pressure.
Indicates that the barometric pressure trend is increasing.
Indicates that the barometric pressure trend is steady.

Barometric pressure display
Press the "REL/ABS WEATHER" key to display the absolute barometric pressure ("Abs" is
displayed on the LCD screen) or the relative barometric pressure ("Rel" is displayed on the LCD
screen).
Note: Absolute barometric pressure is the actual atmospheric air pressure at a particular location
that profoundly depends upon the location altitude. Relative or sea level pressure is the corrected
barometric pressure calculated for the sea or zero level, and usually used to refer atmospheric
conditions.
