Attach the Wind Cups to the Anemometer
The Vantage Vue anemometer measures wind speed. The wind cups are mounted on the
anemometer shaft on the top of the ISS assembly.
1. Gently slide the wind cup assembly
down onto the anemometer’s
stainless steel shaft as far as it will
go, as shown.
2. Use the Allen wrench provided to
tighten the set screw near the top of
the center hub of the wind cups, as
shown. Ensure that the set screw is
screwed in fully and is tight.
3. Pull gently on the hub to ensure that
the wind cups are securely fastened
to the shaft.
4. Spin the wind cups to make sure they
spin freely.
Note: If the wind cups don’t spin freely, loosen the set screw, remove them from the shaft, and repeat
the wind cup installation process.
Attach the Wind Vane
The Vantage Vue wind vane measures wind direction. The wind vane is mounted on a
stainless steel shaft on the bottom of the ISS assembly.
1. Hold the ISS assembly on its side
with the anemometer and radiation
shields on your left, the wind vane
shaft on your right and the wind
cups away from you.
2. When the ISS is held in this manner,
the wind vane shaft is horizontal,
and will orient itself so that its flat
side will be facing to the right, as
shown.
3. Holding the ISS assembly with your
left hand, grasp the wind vane with
your right hand so that the
“arrowhead” end is pointed down.
4. Gently slide the wind vane onto the wind vane shaft, rotating the wind vane slightly
left and right if necessary, until the end of the shaft is visible and protrudes
slightly from the bottom surface of the wind vane.
5. Secure the wind vane to the shaft by firmly tightening the wind vane set screw with
the Allen wrench provided.
Install cups onto
stainless steel shaft.
Tighten set screw
with Allen wrench.
