[CA11] ST60 wind vane issue
Hello,

I have a faulty ST60 wind transducer. I took it apart and powered the PCB with a lab power (8V between red and screen wires). When probing directional signals (blue & green) with an oscilloscope, they appear to output 2-6V sin & cosine which I believe is correct. However, anemometer signal (yellow) outputs approx 350mV pulses while I believe the pulse amplitude should be 5V. Can you please confirm that this is faulty behaviour. If so, please advice on remedy.

Many thanks,

Harri
