2. 1.The Air-Condition Remote Control Multi-Function Tester is a dedicated comprehensive inspection

3. device designed specifically for air-condition remote controls, including TV remotor,industry control remotor,integrating two core modules:

4. electrical performance testing and visual defect inspection. The system adopts

5. a dual-station operating architecture, delivering outstanding testing precision and operational efficiency.

6. It accurately measures electrical performance parameters such as standby current,

7. operating current, carrier frequency, and emission intensity. The equipment is compatible

8. with a wide range of remote control models, supports shielding of designated special frequency bands,

9. and offers customized testing functions tailored to customer requirements.

10. 
    

11. 2.The visual inspection module thoroughly detects various surface defects on the front panel, back cover,

12. standard silk-screen printing, special laser engraving, missing screws, and more. The complete system is

13. equipped with a programmable control system that enables software-based regulation of supply voltage,

14. current, and lighting parameters, making it adaptable to the inspection of air-condition remote controls of all specifications.

15. 
    

16. 3.The system features a straightforward and rapid teaching/configuration process.

17. Once created, inspection templates can be repeatedly recalled, significantly reducing changeover time

18. between product models. The dual-station synchronous inspection mode accelerates production line takt time,

19. shortens per-unit inspection duration, and minimizes manual intervention, making it ideally suited for high-volume

20. mass production scenarios. An automatic unloader is available as an optional component.

21. When equipped, it seamlessly integrates with the production line to enable automated unloading,

22. eliminating manual handling and further saving labor time.

23. 
    

24. 4.Measured production capacity in actual production: With dual-station operation and no unloader,

25. the throughput can reach 600+ units per hour. With dual-station operation equipped with an unloader

26. and without back-side inspection, the throughput can reach 500+ units per hour.

27. With dual-station operation equipped with an unloader and full front-and-back inspection,

28. the throughput can reach 450+ units per hour. For single-station operation,

29. the corresponding capacity is reduced by 200 to 250 units per hour from the figures above.

I. Electrical Performance Testing

• 1. Battery voltage programmable control: polarity programmable,
