10 General information on absolute pressure measurement
The device measures the absolute pressure. This must not be confused with the pressure at sea
level display by weather stations. There the pressure loss due to height above sea level is
deducted. The device is also able to perform this sea-level correction on the displayed air pressure.
Therefore (Sea Level correction) has to be activated (= “on”) and the current height above
sea level (ALTI = Altitude in [m]) has to be entered at the configuration.
