Topic: Barometer Altitude Adjustment

[Phipps]

Newbie here, what is the purpose of setting my altitude on my PWS?

My PWS was showing 28.94 and when I changed the altitude from 0m to 310m my barometer changed to 29.94 and my WU page began showing the higher barometric pressure.

Are barometric pressures always corrected to sea level?

Here is some sensor information:

And here is another one that sounds interesting (I haven't read it yet):

You'll find varying opinions on this forum concerning barometric pressure settings.   

Good luck!

Thanks! I'll check them out.
