Jon, thanks for getting back on this. I’ve noticed that my readings are fine in normal ranges although in higher humidities it does seem to read a few % lower than what surrounding stations are showing. According to the manual 95% is tops on the high end and 20% on the lower. I’m beginning to believe that the accuracy in the low and high ranges ends up to be around +/- 10% or so. Today is the lowest I’ve seen reported from the Portland Jetport weather station in a while at 24%. Surrounding stations vary from 13-28%. So my station at 19% is as good as any. I must say though that all the other readings on my station a pretty much right on. I’m considering upgrading but it seems there is always some type of problem even with the very expensive 1K+. Would appreciate some recommendations.
Peter
