I have the acurite 5 and 1 with PC connect. I received one data point in temp at -40 degrees. Living in San Diego I know this is wrong. Can I clear this on reading, it will forever ruin my lowest temp reading?
Thanks
Not on myAcurite, at least not at the moment.
If it was sent to wunderground, you can go into "table" mode and delete the offending entry.
