The four stages of inspection and testing should be carried out in accordance with the following ten testing steps:
1. Appearance inspection: painting, screen printing, color inspection of the bottom shell/surface shell/lens, rationality and firmness of the production and assembly process of the entire machine. Please refer to the finished product inspection operation manual for the corresponding model
2. The detection of operating functions should refer to the finished product inspection work instructions/product technical specifications of each model:
① The effectiveness test of each button function of the walkie talkie, and the cross test of each button function status. Including unconventional operation of button functions, such as the ability to press multiple buttons at will to observe if there are any abnormalities, etc.
② The detection of low power indication function should meet the requirements ③ LCD display test, check that the displayed content should be correct, without missing or excessive strokes ④ The volume knob and encoding switch should be effective and have good hand sensing ⑤ Use a dedicated headphone cable to test the intercom's call function and it should be normal ⑥ Conduct on-site distance testing and ensure clear communication ⑦ Set QT: 67.0/100.0/254.1, test whether there is communication sound, interruption, blocking, and other phenomena in the call, and randomly set adjacent sets of QTs (such as QT: 67.0/69.3) for two walkie talkies to see if there is any decoding error in the frequency sequence
⑧ Set DQT: 023N/125N/754N, test whether there is communication sound, interruption, blocking, and other phenomena in the call, and randomly set adjacent sets of DQT (such as DQT: 023N/025N) for two walkie talkies to see if there is a phenomenon of serial frequency decoding error 3. Electrical performance index testing: Test various indicators according to the "Product Technical Specification Requirements", and generally meet the requirements of national standards
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
