strange rain total

Post by fotogw » Sat Aug 10, 2019 5:47 pm

Hi,
Today I noticed a strange reading for the rain total: 0,3mm. This should not be possible, since the Davis VP2 is set to 0,2mm and there is a multiplier of 1,05 (No, I'm sure it is not 1,5 :wink: ) set in the station setup. This behaviour was not present before, in july I had readings of 0,2 mm. Updatet to V4.0 end of july.

Meteobridge 4.0 (Jul 27 2019, build 13040), FW 1.4

Any clue what is going on there?
Thanks in advance!

With a rain multiplier of 1.05 and as rain is xx.x mm then sounds like a rounding up?

Hi Matt,
thanks, but 0,2x1,05=0,21... So it cannot be that! The first number to be rounded up would be 1,2mmx1,05=1,26mm>1,3 mm. There seems to be something else going wrong!

Hi Matt,

I guess I was wrong in assuming the multiplier was used on the daily rain total. I think what you meant was this multiplication was done on the yearly rain total, am I right?
