Install the ISS
The anemometer and the main part of the ISS can be installed either together as a
single unit on a pole, or apart from each other. The main part of the ISS includes the
rain collector, the temperature and humidity sensors, the radiation shield, and the
sensor interface housing. Use the U-bolts to install the ISS and anemometer together
or separately on a pole. Use the lag screws to install them separately on a flat,
vertical surface.
• The anemometer comes with a 40' (12 m) cable for flexibility in positioning the
system to monitor wind conditions. For example, the anemometer could be
mounted at the highest point of a roof, and the ISS could be mounted on a fence
closer to ground level.
• If you would like to install your anemometer even farther away from the ISS or
without using a cable, use a Davis Anemometer Transmitter Kit, product number
6332.
General Installation Guidelines
• Install the ISS as level as possible to ensure accurate rain measurements. Use the
built-in bubble level (under the rain collector cone, near the tipping spoons
mechanism) or carpenter's level to make sure the ISS is level.
• In the Northern Hemisphere, the solar panel should face south for maximum sun
exposure, and the anemometer arm should point north for proper wind direction
calibration.
• In the Southern Hemisphere, the solar panel should face north for maximum sun
exposure. Either install the ISS and anemometer separately, each facing north, or
mount them as a single unit with solar panel facing north and the wind vane re-
oriented to the South. (See "Orient the Wind Vane" below.)
Optional: Guidelines for Securing Cables
• To prevent fraying or cutting of cables, secure them so
they will not whip about in the wind.
• Secure cable to a metal pole using cable ties or by
wrapping tape around both the cables and the pole.
• Place clips or ties every 3' – 5' (1 – 1.6 m).
• Mounting clips, cable ties or additional hardware not included with your station
can be easily obtained at a hardware or electronics store.
Note:
Do not use metal staples or a staple gun to secure cables. Metal staples — especially
when installed with a staple gun — have a tendency to cut the cables.
Orient the Wind Vane
The wind vane rotates 360° to display current and dominant wind directions on the
compass rose of the console display. To obtain accurate readings, the vane must be
correctly oriented when mounting the anemometer outside. By default, the wind
vane reports the correct wind direction if the anemometer arm points true north.
