nke wind speed only reads zero

[Argo46933]

Not sure what to do. My nke anonometer only reads zero.
It was working fine. I was playing around with the calibration setting for wind angle and now the wind speed only reads zero.

Sounds like the sensor is not turning. Verify that the cups at the mast head are in fact turning. If they are then you need to take a multimeter and see if you are getting a low voltage AC signal on the wires going into the instrument head.

Not familiar with that particular anemometer but check to see if there is a set screw that secures the cups to the shaft. If that is loose the cups may spin but not rotate the shaft.

Sure your not becalmed?
Try a total reset.

Check the wire connections inside the instrument case. Make sure you have disturbed the polarity.
