calibrated manual gauge, to see if they are
matching or not.
4. Since there may be some water left in the tip
bucket, and also some on the rain collector itself,
the observed rain is normally slightly less than
the actual rainfall, but his is normally within 5%.
If the deviation is larger than this, then you can
change rain calibration settings accordingly, or
contact the customer service for replacement.
Simple way to check the accuracy
1. Take off the rain collector top.
2. Hit the spoon shaped part inside the bucket for 10
times (hit once every 2 second) and see whether
it will register 1.0mm on the console after 5
minutes.
