Hi,
it seems that the mbar seem not accurate. E. g. I know that I life at at an altitude of 915 meter, though the OSTC 4 shows 918 mbar which should be 825 meter.

Is this variation normal?

Regards

Christoph

That's fairly normal as the mbar indication depends on the individual daily barometric pressure.
I don't think your OSTC shows every day the same 918 mbar, isn't it?

Thanks sailor for your reply! Yes correct the OSTC 4 doesn't show every day the same mbar value. Didn't realise that!
