TROUBLESHOOTING
Anemometer
Try dropping the wind cups approximately 1/16” to 1/8” (1.5 to
3 mm) lower on the mounting shaft. Use the included Allen
wrench to loosen and tighten the wind cup assembly.
If you still do not get a reading, the problem is with the anemometer.
Contact Decagon Devices for return authorization.
Problem 2
Wind speed reading seems too high or low.
Solutions
Check installation by spinning wind cups. If the wind cups spin
freely and the weather station displays a wind speed, the wind
cups are installed correctly. If the wind cups do not spin freely,
then try dropping the wind cups approximately 1/16” to 1/8”
(1.5 to 3 mm).
Check for any obstructions blocking the wind near the anemometer.
Problem 3
The wind direction data always reports 0 (North) whenever the wind
speed is zero, even if the wind vain is pointing a different direction.
Solutions
The Em50 uses wind speed and direction to calculate the dominant
wind direction (See page 2.2). Because this calculation uses vector
math, reported wind direction is zero when there is no wind speed.
