So I'm making due on a student's budget and I bought a cheap anemometer. I was just wondering what the best way of verifying the accuracy would be. I thought maybe holding it out of a car window, but I don't know if the aerodynamics would cause the wind speed to be different than the car speed. What about a ceiling fan? Anyone know the range of speed for a typical ceiling fan? I'm reading 3 mph on high... which seems low. Thanks
