Kestrel Instruments Support & FAQs
How come even with the impeller rotating nothing appears on the display except “0” or “--"?
Turn on your unit and remove the impeller. Find a magnet, such a refrigerator magnet. Go to the wind screen and move the magnet in the empty impeller area. If you get numbers other than “0” or “--", the unit is fine and you just need a new impeller. Call 610-447-1555 or visit the Kestrel® replacement parts page for a replacement impeller. On the other hand, if you still only get “0” or “--", please send the unit in for repair.
