ISS Installation Guidelines
10
7. If you are in the Northern Hemisphere, rotate the ISS on the pole so that the solar panel is
facing south; if you are in the Southern Hemisphere, rotate the ISS so that the solar panel is
facing north. The more precisely the solar panels face due south or north, the more accurate
your wind direction readings will be.
Note:
Do not rely on a compass unless it is properly calibrated. In North America there can be up to 15° varia-
tion between true north and a raw compass reading.
8. When the ISS is properly oriented, tighten the hex nuts with a wrench. Do not exceed 96
inch-pounds (10.8 newton-meters) of torque.
Note:
You can refer to the bubble level on the top of the ISS to make sure it is as level as possible.
Finishing the Installation
The wind vane is calibrated at the factory to be accurate when the solar panel is pointing south.
If your solar panel does not point south, you must calibrate your console so that it displays
accurate wind direction readings. In any case, you can also calibrate your console to fine-tune
your station for greatest accuracy. Refer to your
Vantage Vue Console Manual
to calibrate your
console.
Note: Calibration
must
be done if you are in the Southern Hemisphere, or if you are in the Northern Hemisphere
and cannot install your ISS with the solar panel facing south.
Clearing Data Collected During Testing and Installation
Now that the ISS is mounted outside, any data that was collected and stored in the console
during testing and mounting should be cleared.
To clear all the collected data on the console:
1. On the console, press
WIND
so that selection arrow appears adjacent to the wind data on
the display. Confirm that wind speed is displayed on the compass rose.
2. Press
2ND
, then press and hold
CLEAR
for at least six seconds and until you see
“CLEARING NOW” in the weather center.
