The barometric pressure field
Barometric pressure display:
By default the current barometric pressure (HIST = 0) is shown in the
unit mb (millibar) or hPa (hectopascal). However, the display can also
be set to the uncommon unit inHg (inch of mercury). Please refer to
section Basic settings.
The bar graph shows a graphic of the barometric pressure 0, 1, 2, 3,
6 and 12 hours ago.
The barometric pressure trend:
The trend will appear as rising (or dropping), when the
barometric pressure changes by 2 hPa (= 0.06 inHg)
or more within an hour and will maintain the direction for one hour
even without any further change.
At the top right is the barometric
pressure at the time shown in the
HIST field (history).
If LLL (or LL.LL when setting the unit
inHg), the display range is below
850 hPa (25.1 inHg), if HHH (or
HH.HH), it is above.
