The specific steps are as follows:
1. Prepare tools: Find a standard thermometer with higher accuracy than your temperature sensor (such as a second-order platinum resistance thermometer).
2. Measurement and comparison: Heat the PE welding machine to a set temperature (e.g., 200℃). After the temperature stabilizes, simultaneously read the values from your temperature sensor and the standard thermometer, and record the deviation between the two.
3. Adjustment and calibration: Based on the deviation, fine-tune the temperature using the welding machine's temperature controller. Different brands of machines have different adjustment methods; some directly input the correction value, while others require entering calibration mode.
After calibration, remember to check the welding effect to see if the seal is firm and uniform. If you are unsure, you can contact the manufacturer or a professional organization for calibration.
