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

.
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.
The lunar phase:
The current lunar phase is indicated as follows:
The portion of the moon not illuminated will be dark
in the display.
The weather forecast:
The main station calculates a weather forecast for about the next
12 hours based on the barometric pressure trend. Of course this fore-
cast can‘t compare to that of professional weather services supported
by satellites and high performance computers, but merely provides an
approximate indication of current developments. The graphic display
can not be set manually.
Available graphic forecasts are:
slightly cloudy
sunny
