1. Make sure the engraved arrow on the thermo/hygro sensor casing towards the
installation direction of the transmitter box.
2. Align three screw holes on the rain gauge with the three double end studs on
the thermo/hygro sensor casing.
3. Tightly twist the type B screws into the double end studs to make sure the
connection is firmly.
4. Put the rain collector on the rain gauge
aligning the tipping with the holes, and
then twist clockwise to secure it tightly.
5. Put the plastic debris filter in the rain collector.
NOTE Cut away the cable tie on the tipping
bucket before using.

SET UP WIND SENSOR

The wind sensor takes wind speed and direction readings.
1. Loosen the screws in the wind cups and wind vane.
2. Insert the top of the wind sensor unit into the wind cups securely with some
pressure and then twist the screw tightly.
3. Insert the bottom of the wind sensor unit into the
wind vane securely with some pressure and then
twist the screw tightly.
NOTE There is a rubber washer around the top of
the wind sensor for preventing from hard touching
during installation. You can move up the rubber
washer a little bit before inserting the wind cup.

SET UP TRANSMITTER BOX

1. Approach the mounting ring of the transmitter box to the rain gauge, and align
mounting ring with the bottom of the hole of the rain gauge.
2. Insert the mounting insert into the mounting ring of the transmitter box through
the hole of the rain gauge with some pressure. A click sound can be heard.
NOTE The transmitter box contains sophisticated electronic parts, so you must
treat it with care.

CABLE CONNECTIONS

It is better you connect the cables of each sensors
to the transmitter box before positioning the pole.
1. Unscrew to open the transmitter box.
2. Take off the rubber stopper from the cable slot.
3. Insert all the sensor cables through the cable slot.
4. Plug each sensor cable into corresponding
socket that has name below the socket for
recognition. A click sound can be heard.
5. Return the rubber stopper to the cable slot.
