3.1 Unless otherwise specified, the range of environmental or reference point temperature deviation from the specified value during the testing period should comply with the detailed specifications of the device. 3.2 During the testing period, the impact of external interference on the testing accuracy should be avoided, and the testing errors caused by the testing equipment should comply with the detailed specifications of the device.)
During the testing period, the electrical parameters applied to the tested device should comply with the detailed specifications of the device. 3.4 When the tested device is connected or disconnected from the testing system, the service limit conditions of the device should not be exceeded. 3.5 If required, the power supply should be connected in the order specified in the detailed device specifications During the 3.6 testing period, the tested device should be connected to the external network according to the detailed specifications of the device. During the testing period, the tested device should avoid self excitation
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
