INSTALLATION, USE & MAINTENANCE

Remove the two Phillips screws on one side of the rain sensor;

Remove the bucket and remove the black bucket. Pass the cable through the side hole of the chassis and connect the two wires to the four-pin PCB green terminal blocks labeled 3 and 4 on the circuit control board.

Place the control board in the bottom box, align the two holes, and fix the circuit board;

Fix the bucket and the bottom box with screws;

Fix the rainfall sensor on the horizontal arm and use the spirit level to adjust it to the horizontal position. It is forbidden to collide and deform when picking up and placing the sensor;

Do not shift the long fixing screw on the other side of the black dumper, otherwise it will affect the measurement accuracy;

Avoid wearing edges of buckets;

Pay attention to the rain gauge bottom box with one hand, and carefully leave the bucket with the other hand (off the bottom box)

The installation location of the instrument is usually in an open area. There are no big trees or tall buildings to block the precipitation. Try to avoid the leaves and other debris from falling into the bucket, which will affect the normal operation of the rain gauge.
