The impeller does not rotate smoothly and is severely delayed. Due to foreign objects or jamming inside the bearing caused by long term use. Please return the sensor to the company for processing 2. Analog signal, the displayed value is incorrect when RS485 output. It may be due to wiring problems or communicating port failures leading to the inability to obtain correct data. Please check if the wiring is correct and secure, whether the communicating port is in use, and whether the communicating port settings are correct Package List 1 x Wind Direction Sensor
