Cumulus Support

I moved my solar/UV sensor to my anemometer mast and it looks like my plot is shifted slightly to the right of where it should be. I doubled checked that the sensor is level.

I never noticed this before, though my plot was a good bit higher than the theoretical max in the past so maybe not as noticeable - I didn't know it could be adjusted via the transmission factor.

Any guess on what is causing this?

Thanks

It's one of two things: either your latitude setting is off, or the sensor is not level - it doesn't take much to be noticeable on the graph.
