Operation - TFA Dostmann 35.1023 Manual De Uso

10. Operation

After the installation of the Remote Sensors and the following setup of the Base
Unit (test mode of the Base Unit should generally be terminated after the test
mode of the last sensor) the transmitted and computed data will show on their
respective display sections on the LCD. If this is not the case please observe the
notes on debugging on Page 53.
Note!
Please note that data can only be displayed if there is a respective sensor
installed. E.g. without a Rain Volume Sensor there will be no display of rain
volume.
Since all relevant data is simultaneously displayed in the first place, operation
will essentially be limited to simple selection of further sensors or further
weather data by repeated pressing of the respective function keys.
Item „Operation" solely pertains to operation in Normal Mode with the upper key
imprints being applicable.
Programmable functions are thoroughly covered in Item „Programming Mode" with
the lower key imprints being applicable.
Indoor
In normal operating mode the indoor display in the upper left of the LCD displays
the temperature and humidity at the location of the Indoor Sensor.
By once pressing the „Indoor" key the Dew Point will be displayed. The Dew Point
is that point in temperature at which condensation of humidity begins and the so
called "Dewing" takes place, i.e. the humidity is condensing and will precipitate in
liquid form. So the dew point for e.g. air with a water-vapor content of 17.4 g/m 3
lies at a temperature of 20°C.If the dew point for water-vapor drops below 0°C, the
precipitation will take place as snow or hard-frost.The dew point depends upon the
concurrence of a certain air pressure, temperature and humidity at the same time.
By twice pressing the „Indoor" key the temperature display in this section will
change to the display of the Windchill Equivalent Temperature (Perceived
Temperature).
The Windchill Equivalent Temperature (Perceived Temperature) is a fictive
temperature which is perceived by man under certain conditions instead of the
really measured current temperature and which can be taken to determine the
comfort stage of a person wearing suitable clothing at a certain temperature and
wind strength. These conditions are represented by a temperature of 33°C and a
wind strength of 2.6 m/s. Windchill is defined as the cooling effect on bare human
skin at an assumed constant skin surface temperature of 33°C.
The "Perveived Temperature" is approximately comparable to the so called "felt"
