Checking the Anemometer Base Orientation
You will need to know which way to orient the base before installing it.
Insert the anemometer arm into the base
1.
2. Attempt to push the #4-40 x 1 1/4" pan head screw through the holes in the
arm and the base as described in "Attaching the Wind Vane" on page 8.
3. If the screw does not slide easily through the holes, rotate the base 180˚ to
line up the opposite holes, then try again.
4. Note the correct base orientation for use when you install the base later in
the installation process.

Choosing the Best Anemometer Location

Use the following guidelines to determine the best location for your anemome-
ter.
Make sure you install the anemometer in a location where wind flow is
unobstructed by trees and nearby buildings.
For the most accurate readings, the anemometer should be mounted at
least 4 feet (1.2 m) above the roof line.
You may do this by mounting the anemometer on a television antenna
mast, a wooden post, or a metal pipe.
Make sure the antenna mast or metal pipe is properly grounded. You may
want to use Davis' Grounding Kit.
If you are not certain about how to ground your installation, consult a
qualified professional for national and local codes.
Note: If you live in an area subject to frequent thunderstorms, installing a lightning rod nearby can reduce the
risk of damage.
