As a result of internal checking functions, the display of the rainfall is delayed by between 3
and 12 minutes.
2.
Umbrella symbol: shows current rain, i.e. if the rainfall sensor has reported an amount of
rain within the last 15 minutes, which is above the trigger point for the rainfall sensor.
3.
Here, the "Graph " symbol
shows that the trend display for the rainfall has been
selected in the history field. It only appears if it has previously been selected (see 3.2.6.:
"History").
Key functions (Allocation of touch screen fields, see page 11)
-
Touch screen fields 8 and 9 switch over the display mode.
The switching sequence is:
Total, current hour, last hour, current day, last day.
-
If touch screen field 26 ("RESET") is pressed briefly, the point in time at which the total
rainfall data were last deleted will be displayed in the date and time field.
-
If touch screen field 26 ("RESET") is pressed for 3 seconds, the total rainfall value will be
deleted.

Air pressure measurement (fields 10/11)
The display field for the air pressure measurement is situated in the middle at the top right hand
side ("AIR PRESSURE"). Here, the current air pressure at the location of the weather station is
displayed with one of three possible units.

Depending on the setting in the configuration mode, the air pressure is displayed in hPa,
mmHg or inHg.
2.
Either the relative air pressure (value corrected for height, see corresponding setting in
configuration mode and the explanation in the section "Explanation of terms") or the
absolute air pressure (the uncorrected output value from the sensor, right hand diagram)
can be displayed.
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 11)
-
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
height-corrected value for the relative air pressure has previously been entered.

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.

History display (Trend, fields 16-18)
The display field for histories is situated in the middle at the right hand side beneath the air
pressure display. Here, the trend of the values for a selected weather feature is displayed in three
ways:

-
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.
