Ground resistance: no more than0.5 ohm
Insulation resistance: no less than2 M ohm
Starting voltage 85% of rated voltage
3. Noise test
Third, defects and cases
1. The nameplate is curled. When inspecting the goods, it is found that the nameplate with the curled corner is very easy to stick to the plastic packaging bag and tear off when opening the package
2.The design temperature is different from the actual adjustable temperature
3. Temperature conversion between Celsius and Fahrenheit. The product and instruction manual lack instructions on how to convert.
4. Button failure, disassembly inspection found that the button height of the micro switch is not consistent with the design height.
5. Panel corner crack.
6. The sealing strip blocks the rollers of the curtain.
7. The temperature line is hot.
8. Temperature head loosening and displacement.
9. Bad buckle.
10. The injection port is not cleaned.
