Disconnect the charger at the latest four hours af-
ter the completion of the charging process. Other-
wise, the service life of the battery may be nega-
tively affected.

Wind speed:
The wind speed is determined from the rotation speed of the
anemometer. It is important to ensure that the air can flow
directly into the turbine. The wind speed must be at least 0.5
m/s to be measured.
Wind direction:
An electronic compass determines the wind direction in the
range of 0...360°. N = 0°/360°, E = 90°, S = 180°, W = 270°.
To calibrate the electronic compass, press the key
least 3 seconds. The display switches over (see fig.6 and
fig.7). Now turn the sensor 3-4x in horizontal and 3-4x in ver-
tical direction. The direction of rotation can be seen on the
display.

Ambient temperature:
The outside temperature is measured at the unit. To obtain
accurate readings, the unit must not be exposed to sunlight.
Relative humidity:
The relative humidity indicates the saturation ratio of the air,
taking into account the temperature, in percent (%). An air
humidity of 100% means that the air is maximally saturated
Absolute humidity:
The absolute humidity indicates how many grams (g) of water
are contained per cubic metre (m³) of air (water vapour densi-
ty).

Dew point:
The dew point indicates the temperature to which air must be
cooled until it is saturated with water vapour so that it can
start to condense.
The following figure shows the dew point as a function of rel-
ative humidity for different temperatures:

Wind Chill
The Wind Chill (also called wind chill or wind chill)
describes the difference between the measured ambient
temperature and the perceived temperature as a function of
wind speed. It is defined for temperatures below 10°C, be-
cause from this temperature on the absolute humidity of the
air is less than 1% to the air mass, and therefore its influence
on the thermal conductivity and heat capacity is negligible.

Barometric pressure
The pressure corresponds to the weight of the column of air
standing on a body on the surface of the earth. The meas-
for at
ured pressure value corresponds to the actual ambient pres-
sure, not the sea level-corrected pressure.
Category Lighting data
Ambient light
Ambient light is detected by the light sensor installed in the
top of the housing.
Fig. 10
Attention: For correct measurement, it is important to ensure
that the light sensor is free of dirt and that there are no water
droplets in front of the light sensor.
