I've recently installed a National Geographic 7-in-1 weather station (made by Bresser, I believe). Its been working fine and I calibrated the baro sensor from nearby professional stations. I did this by applying an offset to the relative pressure value, which is the pressure corrected to mean sea level I think?
This morning, around 0830, the indicated pressure suddenly jumped up by 7 hPa! I also noticed that the wind speed units had changed from mph to m/s and light intensity units from W/m2 to kLux.
I've no prior experience with this station, having used Davis equipment previously. Anyone know if this is generally reliable? I've applied a new offset to bring the indicated pressure back to the correct value and reset the wind speed and light intensity units but this is somewhat disconcerting!
