Instantaneous value:
The instantaneous value is the gliding mean value of the last second. The scanning of the
measuring values is carried out every 0.25s, and is not alterable. The measuring value, que-
ried at any time, includes always the data of the last second measured in the moment of
query.
Note:
From firmware version V02.09, is the interval of the gliding mean value one
second. All older versions work with an interval of 3 seconds.
Mean value:
The mean value is the gliding mean value of the last ‚n‘ seconds. ‚n‘ is defined by the param-
eter MI.
Minimum:
The minimum specifies the minimum instantaneous value of the last minute.
Gust:
The gust is the maximum instantaneous value of the last minute.
Air pressure:
A highly precise digital pressure sensor (piezoresistive) is used to measure the absolute air
pressure. The wind transmitter calculates the relative air pressure with the set altitude (com-
mand SH).
Note: The absolute air pressure is used for application of the wind velocity compensation by
means of air pressure. Indicating the sensor height by parameter SH is not required.
Inner Housing temperature:
An integrated, digital temperature sensor measures the internal temperature of the housing.
Inclination/vibration:
The measurement of the acceleration in space is done via a 3-axis acceleration sensor. The
wind transmitter will calculate the inclination angle and vibrations (frequency and accelera-
tion).
The inclination measurement is basing on the measurement of the acceleration of gravity.
The three sensitive axes of the sensor are sensitive each only in one direction, thus only that
value of the gravity acceleration is measured which affects in direction of these axes. The
slope of the sensor in space is calculated from these three measuring values.
