A Note on Securing Cables
To prevent fraying or cutting of cables, secure
them so they will not whip about in the wind.
Secure a cable to a metal pole by wrapping
electrical tape around them both. Make sure cables
are secure by placing clips or ties approximately
every 3 – 5' (1 – 1.6 m).

Note:
Do not use metal staples or a staple gun to secure cables. Metal staples—especially when
installed with a staple gun—have a tendency to cut the cables.
If you haven’t used the entire length of anemometer cable, secure the remaining coil by
taping it to the pole, or hanging it on a hook on the post. Place the coil at least 6" away
from the antenna.
Troubleshooting
“The wind cups are spinning but my console only displays zero miles/hour.”
The signal from the wind cups is not making it back to the display. Check your cables
for visible nicks and cuts. Look for corrosion in the WIND jack on the Sensor
Interface Module and on splices in the cable (if any). If possible, remove any
extensions and try using the anemometer cable only. If none of these steps get the
wind speed working, call Technical Support at (510) 732-7814 to ask for a wind test
cable.
“The wind direction is stuck on north, or displays dashes.”
It is likely that there is a short or break somewhere between the wind vane and the
display. Check your cables for visible nicks and cuts. Look for corrosion in the
“WIND” jack on the Sensor Interface Module and on splices in the cable (if any). If
possible, remove any extensions and try with the anemometer cable only. If none of
these steps get the wind direction working, call Technical Support at (510) 732-7814
to ask for a wind test cable.
“The wind cups don’t spin as fast as they should. (Or don’t spin at all!)”
Either the anemometer is located where wind is blocked by something, or there is
friction interfering with the cups’ rotation. Friction usually can be remedied by the
user — remove the wind cups and clear out any bugs or debris. Turn the shaft the
cups rotate on. If it feels gritty or stiff, call Technical Support at (510) 732-7814. 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.
“Wind readings aren’t what I expected them to be.”
Be very careful. Comparing to measurements from TV, radio, newspapers, or a
neighbor is NOT a valid method of verifying your readings. Davis Instruments
sensors are carefully tested at the factory. If you have questions, contact Technical
Support.
