Hi Folks,

After carefully comparing rainfall using both the Davis VP and a
standard manual gauge it seems, in calm weather, my VP is under-reading
by 20%. The tipping mechanism is clean and moving freely.

I know the two screws under the tipping buckets need to be turned
anti-clockwise in order to lessen the amount of rain required to tip,
but can anyone suggest the amount they need to be turned in order to
achieve the 20%?
