Attaching the Wind Cups
1. Push the wind cups up onto the anemometer’s stainless steel shaft.
2. Slide the wind cups up the shaft as far as possible.
Note: Make sure to push the cups onto the stainless steel shaft as far up the shaft as possible.
Failure to do so will cause the anemometer to function improperly.
3. Use the Allen wrench provided to tighten the set screw on the side of the wind
cups.
The wind cups should drop slightly when you let go.
Note: Ensure that the set screw is screwed in fully and very tight. Failure to do so will cause the
anemometer to function improperly.
4. Spin the wind cups.
If the wind cups spin freely, the anemometer is ready and can be set aside while
you prepare the rest of the ISS for installation.
Note: If the wind cups don’t spin freely, take them off and repeat the wind cup installation process.
