New rain-gauge sensor funnel includes a plastic filter intended to reduce maintenance needs. It is
possible that birds or insects construct nests inside the mechanism; so, if it rains and the data does not
look consistent, check your Rain Gauge internally. To open it, just press the lateral walls and pull the
metallic lid. In case of recurrent bird or insect infestation, a good practice is to spray some Diesel or
similar oil inside the Rain Gauge; this will keep them away. If necessary, the Rain Gauge can be
recalibrated – the spoons must tip with 4 ml. This can be adjusted using the white screws underneath the mechanism.

The rain gauge can be recalibrated if this is needed. It should tip at 4ml filled into the double spoon.
The tipping point can be selected by the white plastic screws below the spoon.
