Note: During m/s calibration, thermal probes are adjusted to the annual mean air pressure of
1013 mbar on sea level.
The pressure dependency of the measurement can be compensated by setting the
current absolute pressure in the main menu - SPECIAL - PARAMETER
.
In the case of still air (v < 0.5 m/s) the temperature shown in the display increases
slightly.
