EZ-Mount Advanced Station
Recalibrating the Wind Vane
The wind vane is pre-calibrated as if the anemometer arm were facing west. If
you choose to mount your station in a
different
orientation—for example, in
order to tilt the EZ-Sensor Arm for maximum readings—you need to recali-
brate the wind vane. Otherwise, skip this calibration.
To recalibrate the wind vane, you will need to look at the console display. If
your EZ-Station is mounted on a roof or raised platform, you may wish to have
a friend on the ground do this for you. Or, you may wish to bring the console
onto the roof or platform with you.
1. Use the allen wrench provided to loosen the set screw on the side of the wind vane
and remove the wind vane from the shaft.
2. Press WIND on the console until a wind direction reading and the word DIRECTION
appear on the display.
3. Use a compass or local area map to determine which direction (N, S, E, W, NE, etc.)
the anemometer arm is pointing.
4. Use the wind direction chart to find the
degree reading which corresponds to that
direction.
5. Slowly turn the wind direction shaft with your
fingers. Stop turning when the console display
reaches the degree reading obtained in step 4.
6. Being careful to keep the stainless steel shaft
from turning, place the wind vane on the shaft
with the bullet-shaped nose of the vane point-
ing in the same direction as the arm. Leave
approximately a 1/16-inch (1.5-mm) gap
between the base of the wind vane and the
arm.
7. Use the allen wrench provided to tighten the set screw on the side of the wind vane.
Do not over-tighten.
8. Test your assembly by pointing the wind vane in any direction and—using the com-
pass or map as a guide—make sure the console displays the correct wind direction.
Re-adjust the wind vane if necessary.
