Question [Q] Barometer issue

Hi, I seem to have an issue with the Galaxy S5 Barometer. The value I get is far to low with 957 hPa. The actual value, measured from different weather stations I have, is 1020 hPa. I entered into the self test menu by entering *#0*# but I could not enter or change the value in the Barometer Sensor section. See screenshots attached.
Anyone who has the same issue or an idea how this could be corrected?
Thanks a lot.
