Testing the Anemometer

• Stainless Steel Hose Clamps

• Small Screwdrivers

• Adjustable Wrench

• Hand-Held Compass or Local Area Map

Testing the Anemometer

Before beginning your installation, follow the instructions below to test the

anemometer wind speed and wind direction functions.

1. Connect the anemometer cable to the appropriate connector on your

junction box.

2. Push the wind cups onto the smaller of the two stainless steel shafts at the

end of the arm.

3. Spin the wind cups gently. You haven’t secured them yet, and if you spin

them too hard you may knock them off.

4. Check the display on your weather station to make sure you are getting a

wind speed reading.

5. Grasp the upper, larger of the two stainless steel shafts at the end of the arm

with your fingers and twist the shaft about 1/2 turn.

6. Check the display to make sure the wind direction reading on your display

changes.

Note: The wind direction readings will not change as rapidly as you turn the shaft. The station uses a low

pass filter to smooth out the constant small shifts in wind direction and keep the direction display from

jumping about in gusty winds.

7. Disconnect the cables when you are finished testing the anemometer.

Assembling the Anemometer

Attach the wind cups to the anemometer and check the mounting base

orientation before you install it.
