Height Above Sea Level
+00000.00
(0 to 10000 Metres)
Is the elevation (on the ground) of the unit, relative to the average sea level point.
Atmospheric pressure varies with height above sea level as well as with atmospheric conditions.
As the altitude at which the pressure sensor operates is usually constant (the station height), a
correction is made to make the reading of the pressure sensor seem as if it were made at sea
level. This means that the pressure reading has to be slightly increased from the value read by the
MaxiMet sensor situated above sea level (often known as the station pressure).
Height Above Station
+00000.00
(-100 to +100 Metres)
(Hecto Pascals, Milli-Bars, Millimetres Mercury, Inches Mercury).

ON resets the total precipitation reading to zero when the clock time reads 23:55:59 to 00
(midnight)
OFF results in continuous total precipitation measurement.
