The new calibration factor is derived from the following simple calculation:
Target value (e. g. 7.5 l/m
2
) x old calibration factor
Actual value (display when filled with water)
The old calibration factor (e.g. the current valid value) can be found in the ”Rain-
fall per rocker” input field. If necessary you can also enter the new calibration
value in this input field.
Setting the absolute height
This input field in the “air pressure” menu tab allows the height of the current
location of the air pressure sensor above sea level to be entered. This means
that the air pressure display is adapted to the current location by means of a
correction factor. As a result of this, the relative air pressure is displayed.
Setting the threshold value for sunshine duration
The set-up field in the “Sunshine duration” tab enables the brightness threshold
to be set, above which the light striking the brightness sensor is to be interpreted
as sunshine. This threshold can be set between 2 and 99 klux and is set in the
factory to 20 klux.
A value above the value set is judged to signify sunshine.
This value corresponds to the threshold value generally used in meteorology for
registering the hours of sunshine.
The sunshine duration transmitted from the brightness sensor is used if the
threshold level is 20 klx. For all other values, the program calculates the sunshine
duration from the brightness. The disadvantage of this is that breaks in reception
or large interface storage intervals can falsify the result. This does not occur
when the sunshine duration transmitted from the sensor is evaluated.
Multiple value display
For the temperature/humidity sensors and the wind sensor, the relevant menu
tab will offer you the option of having either the main value (temperature/wind
strength) or both of the generated values (temperature/humidity or wind strength/
wind direction) displayed. To see the relevant secondary value, click on the
corresponding set-up field.
Exit
This menu item is used to close down the radio weather station software.
