Wiring
Tips: Use and maintenance of power transducer
- Regular calibration: After long-term use, the sensor may drift. Regular calibration is recommended to ensure accurate measurement.
- Check the connection terminals: After long-term operation, the terminal screws may loosen, resulting in unstable signals. Check and tighten them regularly.
- Avoid overload: Make sure the input signal does not exceed the rated range to prevent damage to the sensor or increase in measurement error.
- Prevent moisture and high temperature: Excessive ambient temperature and humidity may affect the life of the circuit board. Keep it ventilated and dry.
