I’ve seen several sharp rises and falls with pressure readings since upgrading to 10.21f. See the image below for what it looks like on the graph.
I’m assuming this isn’t ‘real’ given that pressure doesn’t change that quickly, but I could be wrong I guess. I use the height above sea level and use QFE adjust in Units/Other settings to get the relative pressure (no offset on the console).
It’s more of an annoyance than a real problem but I would like to know what causes it. Has anyone else seen this effect?
Dave,
I’m running 10.21e & haven’t seen your problem but I don’t have QFE adjust ticked, should I have & what is it?
I have my altitude entered & presumed the relative pressure was calculated from that
Cheers,
Mark, I am at altitude (well high by AU standards, 450 m :)) and I found if I set the relative pressure on the console it would tend to ‘drift’ over time. I was comparing with two nearby stations and it was pretty clear the console offset wasn’t working too well at my altitude.
WD seems to do a much better job of calculating relative pressure using the QFE setting (more info in this thread). I’m not above 5000 ft but it does get cold here at night, which may be why I have found this setting works best for me.
It is possible the glitch above is due to the weather station console and not WD at all. I was curious to see if anyone has noticed a pressure spike like that with the La Crosse stations.
Thanks for that Dave, I understand it now. Further to our discussion the other day re- humidity, it got to 38.3C here today with a good N wind & the min. humidity was still 18%
Cheers,
