Precautions:                                                               

1. Please confirm that the device has been calibrated before use. If it has not been used for a long time or the sensor has been replaced, recalibration is required.
2. Ensure that the device is fully charged to avoid interruption due to insufficient power during measurement.
3. Do not use the device in environments with high temperatures, high humidity, strong magnetic fields, or corrosive gases.
4. Keep the device stable during measurement and avoid vigorous shaking.
5. It is recommended to calibrate the device regularly to ensure measurement accuracy.
6. Record the data promptly after measurement for subsequent analysis and comparison.
7. Non-professionals are advised not to disassemble the device by themselves to prevent damage to internal components.
