The Taylor Weatherscope Anemometer is a vintage wind‑speed measuring instrument that typically uses a mechanical cup or propeller sensor coupled to an analog output or early digital interface. Common failure points include worn or misaligned cups, corrosion of the shaft bearings, and degradation of the internal potentiometer or signal conditioning circuitry; power supply noise can also cause erratic readings. First‑check steps: verify the unit’s external power supply voltage and continuity on the sensor shaft, inspect for visible wear or debris on the cup assembly, and review any recorded error codes or output waveform anomalies with a calibrated multimeter or oscilloscope.[oss-gpt-20b]
