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,

2. Push the end of the
anemometer cable up
through the square
black grommet into
the transmitter shelter.
Every Davis shelter
has two of these
grommets to provide
weather-resistant
entrances for cables.
In this case, use the
grommet 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.)
5. Locate the DIP switches. You will work with them during the next installation step.
