Weather Data File

This function serves to open stored weather data files and create new ones in
which data in the PC interface can be stored. This means it is possible, for exam-
ple, to create a weather data file for each month and the data to be displayed in
graphical and tabular form as and when desired.

Export

After selecting this function, a window opens in which to select the period related
to which data should be exported and the sensor data required. The selection of
predefined periods enables particularly fast processing. In addition, any target
file can be specified for the data to be exported.

Separators

I

n order to separate individual data (date, time, measured value), several export

formats require the entry of a special separator character which ensures the
data is read in correctly by other programs. The semicolon (;) is frequently used.

Print

I

n order that the developments of weather data can be analyzed over a longer

period of time independently of the PC, it is recommended to print out the rele-
