Preparations

This section describes the working steps and settings necessary in order to start
the sensors and weather station as well as the operating and evaluation soft-
ware.
The outdoor sensors for measuring wind speed, rainfall, outdoor temperature
and relative humidity are equipped with a solar cell for power supply and a lithi-
um backup battery for periods of darkness and bad weather.
To protect the valuable batteries from total discharge during a longer period of
storage without the solar cell being exposed to light, (e.g. storage in its packing),
the power supply for initial operation is activated by a small magnet which must
be inserted from the outside. Therefore, the magnet belonging to the respective
sensor should be inserted just before the sensor is installed outside.
In order to ensure the unique assignment of sensors in the PC interface,
the PC interface should only be put into operation after the sensors have
all been running for ten minutes.
Particular attention should be paid to this because the sensors operate in a test
mode for up to ten minutes after the operating power is applied (inserting the
magnets in the outdoor sensors or inserting the batteries in the indoor sensors).
During the test phase, data is transferred in a 4-second cycle instead of a 3-
minute cycle.
The outdoor temperature and relative humidity sensors must be assigned unique
addresses to ensure differentiation.
Inserting the magnets in the outdoor sensors
In the case of the outdoor radio sensor for temperature and relative humidity, the
magnet to activate the system is inserted in a opening designed for the purpose
in the housing cover.
Activating the wind transmitter is also performed by inserting a small magnet in
the opening provided. The magnet holder is located above the retaining tube
(opposite the solar cell).
To insert the magnet in the rainfall measuring system, the upper section of the
casing must be separated from the lower section by pressing it and turning it
counterclockwise. The housing cover of the funnel integrated in the electronics
casing is equipped with a clip-in holder for the small, round magnet. After press-
ing the magnet into the holder, the rainfall measuring system starts to transmit.
