If Your ISS is Mounted as a Single Unit (Both Sides Together on a Pole)
Unfasten the anemometer:
1. Remove the black rain collector cone from its base by rotating cone counter-clockwise
until its latches line up with openings in the base and you can lift it off.
It is much easier to reach the hex nuts with a wrench if you remove the rain
collector cone first.
2. Using an adjustable wrench or 7/16" wrench, remove the hex nuts and washers holding
the anemometer’s plastic mounting base on the pole.
Set the anemometer down for a moment.
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.
P REPARING THE A NEMOMETER T RANSMITTER
The illustration on the following page 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 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.)
3. Plug the end of the anemometer cable into the receptacle labeled “WIND” on the SIM.
4. Using the 4" black plastic cable tie provided, secure the anemometer cable inside the
shelter.
Slide the cable tie through the cable tie mount, make a loop around the ane-
mometer cable, and tighten.
