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. Check

your cables for visible nicks and cuts. Look for corrosion in the WIND connector

on the sensor interface and on splices in the cable. If using an extension cable,

remove it and test using only the anemometer cable. Contact Technical Support

and ask for a wind test cable if the problem has not been resolved.

Note:

If the anemometer is not sending data, the wind display indicates 0 speed and "--" for

direction.

"The wind direction is stuck on north, or displays dashes."

It is likely that there is a short somewhere between the wind vane and the display.

Check the cables for visible nicks and cuts. Look for corrosion in the "WIND"

jack on the sensor interface and on splices in the cable (if any). If possible,

remove any extensions and try it with the anemometer cable only. If none of these

steps get the wind direction working, contact Technical Support and ask for a

wind test cable.

"The wind cups don't spin or don't spin as fast as they should."

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 insects or debris. 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 rubbing against any part of the anemometer head.
