11 Connecting to a PC – Installing software
The following system prerequisites apply to operating the
"WeatherPro Edition 2007" software:
· Windows 2000/XP operating system
· Min. 1 GHz processor clock speed, min. 256 MB RAM
· Approx. 150 MB hard disc space available for the program
· Approx. 100 MB hard disc space available for the database
· The file system must be formatted with NTFS (standard option).
· The Windows Installer Service must be installed (standard option)
The supplied USB cable featuring a type A connector and a mini type B connector, 5-pin,
is needed to connect the product to a USB port on the PC.
- Use the USB cable to connect the weather station to a USB port on the computer.
- After a short time the PC will register the presence of a new USB device and detect a
driver. The installation wizard appears.
- Insert the CD-ROM supplied and wait until the welcome screen appears.
- Now return to the installation wizard and select the "Find automatically" option.
- Follow the installation wizard instructions until installation of the driver is complete.
- Now return to "WeatherPro Edition 2007 Setup", where the four set-up steps are de-
scribed. Start here at point 2.
- Follow the instructions step by step until installation is complete.
The "WeatherPro Edition 2007" program can then be opened via the desktop or the
program menu.
- You can find a description of the program in the help menu under "Manual".
Firmware update
The firmware of the WDC7000 main controller can be updated via the WDC7000 USB
interface using the software supplied.
- In the "WeatherPro Edition 2007" software, start the update program ("Tools" menu,
"Firmware Update" menu item) and follow the program instructions.
Note:
If you have started the update procedure by mistake, it can be cancelled at any
time up to step 5. If update mode has also been activated on the device as per
the software instructions, disconnect the weather station from the USB and the plug-in
main adapter for a few seconds and remove the batteries from the device. This will not ad-
versely affect the function of the device, which will continue to run with its existing firmware
following restart.

Apparent temperature - Refer to wind chill
Dew point - Temperature point that is dependent on a specific barometric pressure, a
specific temperature and a specific humidity coinciding. At this temperature point the hu-
midity starts to condense and is deposited as a liquid (mist or vapour). If the dew point
for water vapour is under 0˚C, the condensation takes the form of snow or frost.
Weather forecast - Forecast indicator using weather symbols, calculated from the rate
at which the barometric pressure rises or falls (trend).
This rate of change in the barometric pressure is the decisive factor in forecasting the
weather to come, with the absolute value playing only a minor role. As a general rule,
rising barometric pressure indicates better weather and falling barometric pressure
indicates poorer weather.
Wind chill equivalent temperature (apparent temperature) - This is a notional tem-
perature felt by people under certain circumstances, rather than the actual measured
temperature. It can be used, for example, at low temperatures (e.g. under 7˚C) to indica-
te how people will actually feel at certain temperatures and wind velocities and wearing
appropriate clothing. The conditions at which the wind chill comes in to play are when
the temperature is below 33˚C and the wind velocity is over 2.6 m/s. The wind chill is de-
fined as the cooling effect felt on uncovered skin with an assumed constant skin surface
temperature of 33˚C.
The higher the wind velocity and the lower the actual temperature, the more pronounced
the wind chill effect.
The "apparent temperature" is more or less comparable to the perceived temperature,
which also takes the effect of the sun's rays, the reflection of light by the clouds and the
light wavelength, etc. into account.
