Installing 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
SIM 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 configuring the sys-
tem 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.
General ISS 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 bucket mech-
anism) 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.
• 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.
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 approximately 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.
To ensure correct orientation of the wind vane, mount the anemometer so that the
arm points true north.
The wind vane will be ready for use immediately.
If your anemometer arm cannot be mounted aiming true north, you will need to
calibrate the wind direction on your console to display accurate wind directions. See
your Vantage Pro2 Console Manual.
