This thing works!
Perhaps some of the negative reviews that I saw earlier (now removed) were from folks who didn't understand some of the really neat features of this gadget. The product description doesn't do it justice. The only reason I gave it less than a perfect score is after some brilliant design work, some yo-yo gave it a tinted plastic front which makes it difficult to read at times. Now, you do have to experiment a little as the manual supplied wasn't really clear. So, here is how to check it out: This assumes that it is raining out, which complicates the issue. Turns out it is quite accurate (compared to my old "passive" gauge). First verify that it is working properly. If not, it may be necessary to remove the sensor housing and make sure the rain bucket moves freely. With the sensor next to the display, you should see both in and out temps (see manual). Now advance the mode until it shows current rainfall. This reading can be reset by the Clear button. This is the only thing the clear button does, all the history readings remain in memory until you remove the batteries. Now pour a measured 20cc of water into the sensor funnel. Slowly, as the bucket should only trip about every 10 sec to get an accurate reading (you'll hear it click). Each bucket holds 4cc and 5 bucket trips will measure indicate .1" rain. Strangely, starting from 0, the first 5 only measure about .08". No big deal. Now you can place the sensor outside and verify the signal is good by doing the rain test again. Assuming it rains where you are, the rest is very clever. As the days pass, a day's rainfall moves to the left for each day. After that you can push the History button to see totals by the week or month. Hey! You could put the sensor under your sprinkler to verify how much water your grass gets every day. Very clever gadget. BR
