Check whether the wiring part is firm and whether the screws are loose
2. Resistance value measurement:
Use a multimeter to measure the resistance value of the heating tube. Adjust the multimeter to the appropriate resistance position, and the resistance value of the heating tube should be within the specified range.
3. Power-on test:
Ensuring that the wiring is correct, Perform power on test. Observe whether the ammeter reading meets the standard.
If the current is too large or too small, it may indicate that there is a problem with the heating tube.
4. Temperature measurement:
After powering on for a period of time, use a thermometer to measure the surface temperature of the heating tube.Make sure that the surface temperature is within the rated temperature range.
