Cumulus Support

Hi
I have replaced my FO station with one from Clas Ohlson (brilliant service) and as it was previously faults with the anemometer and transmitter I can run two displays. Oddly they have quite big differences in the pressure readings (7mb). It doesn't particularly matter as I can set them to my local met station - just interesting.
Regards
Alan

Mine is about 114 hPa out, but so long as the offset is configured correctly it works OK

According to the device specs, given manufacturing differences, supply voltage differences, temperature, drift with age, quantizing errors, and so on, it's possible to see up to 20 hpa between 2 units.
