I Own a Model 01212DIA3 5 in 1 weather station, During a Recent Storm I was reporting what I thought was an accurate Barometric Pressure on Facebook. Come to Find Out The local National Weather Service reading and the my Android Cell Phone Barometer app are within .01 In Hg! My Acurite is Barometric Pressure reading is -.30 In Hg , Totally unacceptable! I read several threads pertaining to this and there is no calibration adj! As far as the Learning mode goes mine has been connected for months! I realize this is an inexpensive unit but it should be able to be calibrated Based on Location! What ever happened to your proposed Atlas Line?? Any Answers on a Correction?
