The measuring range depends on the sensor type.(see data sheet)
The range, the units (2 characters), and a designation are programmed automatically;
this designation comprises the familiar abbreviations listed in tables issued by the
Deutscher Wetterdienst (German Meteorological Service) and the newer symbols de-
fined in VDI/VDE 3514.
