my anemometer has stopped transmitting accurate wind speed, never goes above 2mph, battery good, I have tried resetting the unit.   Any other ideas.   what is the rpm to wind speed relationship so i can re-calibrate the gonometer. Unsure as to model number but it is a 5 in 1

You could try partial dissassembly and oiling it.

The cups rotate freely,  I will pull it down and disassemble to clean it.

Maybe the magnets aren't close enough to the sensor?
