Re: ST60 Wind Transducer - What does this Test Show?
The wind vane
outputs a chopped 8 volt square wave.
It increases in frequency but not amplitude as the wind
The 8 volts is supplied by the display.
All you need to see is if the 8 volts is there and if it goes up and down when you turn the paddles.
