3. Remove the hex nuts and washers holding the rain collector side on the pole.
Retrieve the U-bolt that was holding the anemometer.
4. Using the washers and hex nuts, fasten the rain collector side back onto the pole.
Flat washer goes on first, then lock washer, then hex nut.
5. Put the rain collector cone back on. Rotate the cone clockwise until the latches
slide into place.
If Your Anemometer is Mounted by Itself
Unfasten it: use an adjustable wrench or 7/16" wrench to remove the hex nuts or lag
screws.
Preparing the Anemometer Transmitter
The illustration below shows the Sensor Interface Module, or “SIM”, inside the
transmitter shelter.
1. Insert the 3-volt
lithium battery into
the battery holder,
matching the “+”
sign on the battery
with the “+” sign on
the SIM.
2. Push the end of the
anemometer cable up
through the square
black grommet into
the transmitter shel-
ter. Every Davis
shelter has two of
these grommets to
provide weather-
resistant entrances
for cables. In this
case, use the grom-
met on the right. You
can also remove the
grommet, thread the
cable through it and
then replace the grommet in the shelter if that is easier for you.
3. Plug the end of the anemometer cable into the receptacle labeled WIND on the
SIM.
4. Place the cable clamp over the anemometer cable between the grommet and the
receptacle. Secure the cable clamp to the shelter by threading the provided #6
screw through the washer, then cable clamp and then screwing it into the cable
clamp mount inside the housing. (See the above illustration.)
