Most Common Anemometer Problems
“The wind cups are spinning but my console displays 0 mph.”

The signal from the wind cups may not be making it back to the display. 
Remove the cups from the anemometer (loosen the set screw). Put the cups back 
onto the shaft and make sure to slide them down the shaft as far as possible. 

The anemometer may be located where wind is blocked by something, or there 
may be friction interfering with the cups’ rotation. Remove the wind cups 
(loosen the set screw) and clear out any bugs or debris which may be interfering 
with the cup rotation. Turn the shaft the cups rotate on. If it feels gritty or stiff, 
contact Davis Technical Support.

Note: 

Do not lubricate the shaft or bearings in any way. When replacing the cups, make sure they are not rub-
bing against any part of the anemometer head. 

Comparing data from your ISS to measurements from TV, radio, newspapers, or 
a neighbor is NOT a valid method of verifying your readings. Readings can vary 
considerably over short distances. How you site the ISS and anemometer can 
also make a big difference. If you have questions, contact Davis Technical 
Support. 

If you have questions about the ISS or Vantage Pro2 system, or encounter problems 
installing or operating the weather station, please contact Davis Technical Support. 

Note: 

Please do not return items to the factory for repair without prior authorization.
