→‎Cumulus doesn’t show the same pressure as my Fine Offset console
Normally when Cumulus starts, it reads in [http://www.jim-easterbrook.me.uk/weather/mm/ the fixed block] in the console a pair of absolute/station pressure and relative/sea level pressure readings and uses the difference between these as the ‘offset’ in millibar for the station; Cumulus uses this offset subsequently to calculate the sea level pressure (each time when reading the absolute pressure in the weather memory locations of the station), but it is possible to define the offset in '''Cumulus.ini''' instead.
 
{{Version badge 1}}'''IMPORTANT''' TheThese abovenotes appliesapply to Cumulus 1. bvs79669 did some investigation in January 2019 that reveals the mapping of memory bytes to pressure reported by Jim Easterbrook and used by Steve Loft is wrong. The two most significant bits included in the mapping create impossibly high readings for pressure. From build 3047, MX excludes these two bits when reading the pressure and the reliability of reading correct pressure from a Fine Offset station has been significantly improved.
 
Make sure that you have set your console's relative pressure correctly:
