Troubleshooting

While your anemometer is designed to provide years of trouble-free operation,

occasionally problems may arise. If you are having a problem with your unit,

please check the following troubleshooting procedures before sending the unit

in for repair. You will be able to solve many of the problems yourself. If, after

checking these procedures you are unable to solve the problem, please call

Davis Technical Support for further instructions (

see “Contacting Davis

Instruments Technical Support” on page 8.) Please do not return your unit for

repair without receiving prior authorization from Davis Technical Support.

Wind speed reads 0 all the time or intermittently or wind

direction reading is dashed out

• Make sure anemometer is plugged into jack marked WIND on junction box.

• Check for broken wire along length of anemometer cable. Carefully check

areas where the cable has been secured.

• 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

retighten the wind cup assembly.

• If you still do not get a reading, the problem is with the anemometer. 

Contact Davis Technical Support for return authorization.

Wind speed reading seems too high or too low

• 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 don’t spin freely, then try dropping the wind cups

approximately 1/16" to 1/8" (1.5 to 3 mm).

• Check calibration number and adjust if necessary.

• Check for any obstructions blocking the wind near the anemometer.
