Infrared sensor calibration in the web guiding system

For some materials that are not easy to identify, the infrared sensor is required to achieve the best web guide effect.
Steps
1. Long press the "SET" button to make the sensor light flash (release the button after flashing)
2. Tighten the material and put it into the position of the sensor near the light lens (the material will completely cover the circular light-transmitting sheet). Then wait for 3 seconds and remove all the materials from the sensor
3.Press the "SET" button until the light does not flash, and then release the button. The process of the calibration has been completed.
