Reducing temp fluctuations

Hi Brian

Is there a way to moderate temperature fluctuations with the Lacrosse 2010? (I know…the BEAST!)
Sometimes my graph show ups and downs of 4 or more degrees in less than 15 minutes when I’m sure the real temp is some average of it all.

It tends to make the graph rather saw-toothed when I’m sure actual temp changes are a little smoother. Plus it reeks havoc with daily highs and record temps. Do other type stations do this?
Is it a fixable thing? …some kind of running average maybe?

Thanks - Keith
