Pressure Readout

Post by JohnBaloo »

Hi,
I hope this is the right place to post, my system seems to have developed an error. On the weather station display it gives one value for the pressure but cumulus gives another (i.e. weather staion display is 1011.12 and the sofware is showing 1024.1) is there somewhere I can edit this as the weather station seems to closer in value to other stations close to me including Gatwick Airport.
Thanks
John

You need to calibrate your weather station's relative pressure reading so that it matches a nearby reference. Instructions for adjusting the setting are in the manual. If you don't have one, there's one in the wiki: http://wiki.sandaysoft.com/a/Fineoffset_manual. The bit you need is on page 10 in that version.

When you've set the relative pressure, you need to restart Cumulus to get it to pick up the new setting.
