[Relative Pressure Query on New Weather Station]

When I used the calculator I though that the results seemed very high. But thought I better ask. Thank you for your reply I think I'm leaving it as it is and see how that goes. Thanks for the link as well it looks interesting. It's always fun where we live looking at the wind speed and wondering if the roof is going to stay on  Phil

[Relative Pressure Query on New Weather Station]

Hi

I've just bought a new weather station (Bresser 7 in 1) I am pretty new at this kind of thing. I'm trying to figure out the offset for the relative pressure. My station at the moment shows a pressure 989.8hpa. I've used the calculator (temp 8.9, alt 275m and pressure on station 998.8) and that shows Sea-level pressure of 1023.69hPa. Does this seem right? and what would that make the offset to enter into the station. Thank you for any help you can give. The station itself appears to be pretty good. I've linked it up to AWEKAS and am very impressed.

Thanks
Phil
