Installing the DS-2
5.1

Attaching and leveling

The DS-2 is fitted with a U-bolt, allowing it to be mounted atop
most posts, poles, tripods, etc. Depending on the application, the
DS-2 should be mounted two to three meters above ground.
5.1.1

Adjustable Length Pole

A telescoping pole is available for purchase to use with the DS-2. The
pole consists of two tubes, which can be adjusted out to a length of
approximately 2.38 meters. The large, outer tube has a diameter of
approximately 5 cm, whereas the inner tube is approximately 4.5 cm
in diameter.
Be sure to secure the pole to the ground by either auguring a hole
(we recommend .6 m, or 2 foot depth, minimum), or by any other
means available.
5.1.2

Leveling

You will need to adjust the anemometer so that it is level. Use a
bubble level or other leveling device to ensure the anemometer is
level(leveling device not included).
5.2

Orientation

For accurate wind direction measurements the DS-2 must be prop-
erly oriented. An N engraved on the side of the anemometer indi-
cates which side of the sensor to point north. Be sure to direct the
anemometer toward true north, not magnetic north.
