Rain gauge

Brian:

I have been noting that WD, when it rains very softly, does’nt show thw rain values as the Davis Weather Monitor II data logger. For instance, today, I had 0,4mm at Monitor II and 0,0mm at WD. It was raining very softly indeed. Then I corrected WD to show 0,4mm and when the data logger registered 0,6mm WD did the same thing. In the station setup I have setted a 0,2mm rain gauge. Any ideas?

Cheers
