“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 up the shaft as far as possible. Check your cables
for visible nicks and cuts. Look for corrosion in the WIND connector on the SIM
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 sending no data, the wind display indicates 0 speed and a orth 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 SIM 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 bugs 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.
“Readings aren’t what I expected them to be.”
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 Technical Support.
