3.Here, the “Graph” symbol 
shows that the trend display for the air pressure has been selected in the history field. It only appears if it has previously been selected (see section on “History ”).
If the air pressure history is active, then the tendency indicator for the development of the air pressure will also appear next to it on the right.
Key functions (Allocation of touch screen fields, see page 9)
-You can switch between displaying the absolute and the relative air pressure using touch screen fields 10 and 11.
Please note!
A difference between the absolute and relative air pressure will only be displayed when the
3.2.5.Weather forecast
Based on years of experience in the development of weather measurement technology, the weather forecast algorithms for the actual operating location of the weather station are very sophisticated and reliable. Owing to comprehensive data capture, the calculation of weather tendencies is accurate enough for these types of devices as well, so that, for example, the weather station will not be “fooled” by a short period of sunshine just before a long period of rainy weather sets in. The comprehensive nature of the forecast depends also on the location of the sensors; in flat countryside a comprehensive forecast of this sort is possible, whereas in mountainous regions the conditions change more frequently and are more localized.
The weather forecast is shown in the middle of the display underneath the rainfall indication by means of easily remembered weather symbols.

The trend values for the last 24 h or for the last 8 days are displayed.
The minimum values for the last 8 days are displayed.
The maximum values the last 8 days are displayed.
-The sensor for which the trend is to be displayed is selected by first pressing touch screen field 16.
-The request “SELECT ” then appears.
-The field is then touched for which the trend is to be displayed.
-The display mode is switched over between the trend for the last 8 days and the last 24h using touch screen fields 17 and 18.
-The respective scale factor is shown above the graphical trend display. The different scaling is necessary in order to be able to clearly show large variations and different trends within the available graphics field.
