PC Connection
As an important feature in addition to the display on the Touch Screen, the Weather Station allows the read-out of all
measured and displayed time and weather data in form of complete history data sets on a PC.
Data Storage
For a comprehensive weather history, the Base Station allows the internal storage of up to 4080 complete sets of
weather data with time and date. The base station will loose all weather data if an interruption of power supply. In case
the memory capacity of the Weather Station is exhausted the oldest data sets stored will be overwritten by the new
ones entered.
Data Recall
Certain weather data or setting values can only be read out, processed, and displayed by means of a PC. Also the
settings of the storing intervals from 5 minutes to 240 minutes for the storage of data sets can only be performed by
means of a PC.
Connections and Software
The wiring between Weather Station and PC takes place by means of an included USB cable. The EasyWeather
software package, also included in the shipping contents, must be installed on the PC.
This software allows the display of all present weather data with graphic symbols. It also allows the display, storage,
and printing of history data sets, whose volume exceeding the maximum 4080 data sets of the Weather Station is only
limited by the capacity of the PC’s main memory.
PC software installation
The installation of software is very simple: double click the setup.exe file and follow the steps popped up.
Make sure you are running the program under the administrator accounts of your windows PC platform. Otherwise the
graphic function might not be working when graph display mode is needed to display all history data.
If you run the program for the first time, the current weather display will be displayed and at the sub line of the window,
the program will show related information regarding the read of all history data into the PC. Please note however, when
there is large amount of data is being uploaded, it will take a few minutes time before the system can respond to your
setup settings. Otherwise it will display “read weather data fail” error message since the USB port is reading the data
from the memory and the system is not able to respond any further job tasks.
When memory is full, it will take about two minutes to upload all history data into PC and it takes another two minutes to
process all history data for graphic display. Further detailed PC software user manual can be found from the help menu.
