I have a Vantage Vue and I'm thinking the rain isn't very accurate. Since midnight it's showing 0.61 total. My father lives about 2-3 miles away and has the same station. His reported 1.09. So , I checked Weather Underground and someone in the very next neighborhood shows 1.11 since midnight. I guess it's possible I got less rain but I'm not sure.
That got me into looking at the manual. I do see a method of calibrating rain on page 28 which has to do with percentages. It does mention that it can only go from -25% to +25%. Just not sure if I should try and adjust.
Is there not a way of pouring a pre-measured amount of water into the unit to verify?
