[CA] [CA11] ST60 wind, tested voltage

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum gk1978c34,

Per the FAQ addressing how to test a masthead wind transducer, yellow to shield should read between 0V and 5V DC (the exact voltage depends on the instrument: 3.2V is typical for ITC5, more like 5V on ST60.). This is the wind speed signal. The voltage will toggle between 0V and the maximum (3-5V), twice per rotation of the anemometer cups. At low wind-speeds you'll see each individual pulse, but at higher wind-speeds your multimeter will average the voltage, in which case the the faster the wind is blowing, the higher the voltage will read. Accordingly, should the cups be rotating in a decent breeze, then a non-zero (averaged) voltage should be seen on the multimeter. If not, then the masthead wind transducer should be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
