Precautions:

1. During the welding, installation and use of the sensor, the gold-plated plastic cavity should be protected from any direction pressure.

2. If the sensor needs to be placed in a small space, this space should be well ventilated, especially the two diffusion windows should be in a well-ventilated position.

3. The sensor should be far away from heat sources and avoid direct sunlight or other heat radiation.

4. The sensor should be calibrated regularly, and the calibration period is recommended not to exceed 6 months.

5. Do not use the sensor for a long time in an environment with high dust density.

6. To ensure the normal operation of the sensor, the power supply voltage must be maintained at (5.0±0.1) VDC. Power supply current is not less than 150Ma

7. If it is not within this range, it may be that the sensor is faulty, the sensor output concentration is low, or the sensor cannot work normally.

8. When manually calibrating the zero point or sending a command to calibrate the main point, it should be stable

9. Work continuously for more than 20 minutes in a gas environment (400ppm).

10. The sensor prohibits the use of waves with the maximum depth.

11. When soldering with a soldering iron, set the temperature to (350±5) degrees, early

12. The pick-up time must be less than 35.

13. When using the sensor, it is recommended that the customer use the welding punch insertion method to directly insert and remove the sensor.
