I sure am gratefull for your reply. I had seen the tabs, yet the base/cover looks so seamless, I was afraid to go prying on it. I got the unit secured now, (I was concerned the wind would knock it over and disrupt the paddles).
We have had a lot of mist and drizzle for a few days straight now, I had my weather station set up for 24 hours now. I noticed on the history data page that at times the cumulative rain total was increasing by 3 or 4 Hundreths !! I am impressed with the sensitivity of the measurement. The first 12 hours of my rain total, matched that of my Uncles traditional glass tube rain gauge.
Thanks again for your responce to my question.
