Choose the Mounting Location
Choose a location that is free of turbulence and magnetic fields resulting from
electricity, engines, radio transmitters, radars, etc.
Tip:
Mount the anemometer where it will receive direct sunlight for several hours each day.
Anemometer Siting Guidelines
• For best results, place the anemometer at least 7' (2.1 m) above surrounding
obstructions such as trees or buildings that obstruct wind flow.
• If mounting on a roof, mount the anemometer at least 7' (2.1 m) above the roof
apex (when using a Mounting Tripod, install the anemometer at the very top of
the pole).
• If mounting the sensor suite and the anemometer together, such as on a pole or a
wooden post, mount the anemometer so it is at least 12'' (0.3 m) above the top
of the rain collector cone for best results.
• The standard for meteorological and aviation applications is to place the
anemometer 33' (10 m) above the ground. Seek professional help for this type
of installation.
• The standard for
agricultural applications
is to place the anemometer 6' (2 m)
above the ground. This is important for evapotranspiration (ET) calculations.
Note: Note: For more detailed siting suggestions, see Application Note #30: Reporting Quality
Observations to NOAA on the Davis Support web site (http://www.davisnet.com/support/weather).
Connect the Battery
The anemometer includes a factory-installed battery which has been
disconnected for shipping. This battery is charged by the solar panel, so you
should not connect it until you are ready to install the sensor. Once it is
connected, it will lose charge in about 10 days without sunlight. The sensor
may need some time in the sun or under a lamp to charge.
1. Connect the two battery cables. (See illustration on page 2.)
2. Push the connected cables into the tube.
3. Push the cap into the end of the tube to seal it.
4. Mount the anemometer in sunlight within 10 days of connecting the battery.
