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 check-
ing these procedures you are unable to solve the problem, please call Davis Tech-
nical Support for further instructions (see "Contacting Davis Instruments
Technical Support" on page 11.) 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
• Make sure anemometer cable is plugged into the jack marked WIND on the
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 probably 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
your weather station displays a wind speed then 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.
Wind direction reading is dashed out
• Make sure anemometer cable is plugged into the jack marked WIND on the
junction box.
• Check for broken wire along length of anemometer cable. Carefully check the
places where the cable has been secured.
Note: If these steps do not solve the problem, the problem is probably with the anemometer. Call Davis Tech-
nical Support for return authorization.
