==Setting the Datum==
All weather stations allow you to adjust the pressure for sea level. You should not make the adjustment within Cumulus.
For Fine Offset see [[FAQ#Cumulus_doesn.E2.80.99t_show_the_same_pressure_as_my_Fine_Offset_console]].
The best way to get MSL pressure at your location is to go to a site like [http://www.wunderground.com/ Weather Underground] and enter your location. It will find a weather station nearby and give you the current MSL pressure. It's a good idea to choose an airport site because you can be sure that it has been accurately reduced to MSL pressure.
Alternatively, look at a isobar chart at a site like [http://www.meteorologica.info/UKisobars.htm weather superstore], and interpolate for your location.
The best time to set your datum is when the pressure is
== Calibration ==
If you find that your sensor is inaccurate, it may be possible to apply a calibration within cumulus (configuration menu).
