Bresser 3 in 1 (7002535)

[Guest ventnorvisual]

After dome and help with my station, 

I have set up a Bresser 3 in 1(7002535 moder). Everything is good and it sends its data out across the web no problem using Wunderground but cannot find how to adjust the barometric pressure to my specific location. Just wondered if anybody could advise on my problem for me.  I guess precise barometric pressure doesn't matter but it seems to be a good 8 hPa out to sea level pressure. Any advice very much appreciated

Hi, looking in the manual it suggests that you can add an offset for you height above sealevel, here

There are several ways to calculate this, as you need to determine your height above sealevel so you can then set the offset.
