Reply To: Rain gauge gets stuck

There should be little adjustment screws or stops that allow you to calibrate the sensor to tip at exactly one millimeter of rainfall (which is 5.0 ml of water).  Did you try adjusting them and doing the calibration procedure before deployment?  You also have to ensure that the sensor is installed completely level and that it is mounted to a firm pole or mount that doesn’t move.  If any tipping bucket rain sensor is installed unlevel, it can cause accuracy issues and improper operation.  We’ve also encountered spiders that make webs during dry periods that can cause them to not tip properly during rain events (I don’t think that’s your current issue, but it’s something to watch out for on long deployments.)
