2.29? But it does seem physically impossible. The highest I've seen is I think 7 or 8" per hour, or maybe only 6". > Davis VP2 spec sheet says the max range for rate is 30 in/hour so I can't > explain why his db shows many archive periods well over that number. There's the highest actual rate that will measured correctly, and then there's the rate that the instrument is guaranteed not to report. I'd expect 30 in/hour to be the highest real rate that will result in valid data. I find that rate to be comfortably 4x the highest rain rate I've ever experienced, and it seems a good design point. > Range. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . > . . . . 0, 0.04"/hr (1 mm/hr) to 30"/hr (0 to 762 mm/hr) That's almost a tip per second. No reason the computer couldn't count it.
