5. إجراءات الاختبار

5.1 Using It as a Power Source

Ensure that all devices are powered off; use a test cable to connect the device’s output port to the DUT’s power input port; after setting the desired power output parameters as described in Section 4.1.1, start the output; when finished, click “Disconnect Output” again.

5.2 Standard Operational Testing

5.2.1 الأسلاك

Ensure that both the device and the DUT are powered off; use a test cable to connect the device’s output port to the DUT’s power cord.

5.2.2 الاختبار التشغيلي

First, refer to Section 4.1.1 to set the appropriate power supply parameters for the DUT and enable the power supply output, ensuring that the DUT is in normal operating condition.

Then, refer to Section 4.1.2 to select the required test standard or configure the test parameters, and run the test; observe the DUT’s operating status and record any observations; wait for the test to complete—or, in case of an emergency, press the stop button to halt the test immediately.

5.2.3 تقييم النتائج

المستوى الوظيفي	Definition of Standards	Judging Guidelines
الصف	During and after the application of interference, all functions of the DUT operated normally as designed, and performance parameters remained within specifications.	No functional abnormalities were observed throughout the entire process, and no intervention was required after testing—this meets the highest standards.
درجة ب	During the application of interference, all functions remain operational, but certain parameters may exceed their tolerance limits; once the interference is removed, all functions automatically return to their normal ranges, and the storage function maintains Class A performance.	Parameter drift and minor performance degradation are permitted during testing, but no functional failures may occur; the system must automatically recover after testing.
الصف C	During the application of interference, one or more functions do not operate as designed; once the interference is removed, the functions automatically return to normal.	During testing, phenomena such as functional interruptions and logical anomalies are permitted; after testing, the system should recover automatically without the need for manual intervention.
الصف د	Malfunction occurs while interference is present; after the interference is removed, normal operation can be restored only through simple manual steps (power cycle, reset).	Freezing, rebooting, and similar issues are acceptable, but there must be no hardware damage, and the system must be able to recover with a simple reset.
الصف E	During and after the interference, the function will be permanently disabled and cannot be restored without repairing or replacing the hardware.	Permanent damage; automatically deemed a failure

Core Principle: If the DUT exhibits a Grade E performance (hardware damage, permanent loss of functionality), the test is deemed a failure regardless of the agreed-upon grade; for Grades A through D, pass/fail is determined based on the minimum acceptable grade agreed upon by the supplier and the customer.

5.2.4 إجراءات ما بعد الاختبار

تأكد من إيقاف تشغيل كل من الجهاز والجهاز قيد الاختبار؛ افصل الأسلاك من جانب الجهاز قيد الاختبار أولاً، ثم افصل الأسلاك من جانب الجهاز.

6. الصيانة اليومية للمعدات والعناية بها

6.1.1 جدول وإجراءات التنظيف

بعد كل استخدام: نظف سطح شاشة اللمس وأزل الغبار من لوحة الجهاز؛

أسبوعيا: نظف غلاف الجهاز والفلاتر الموجودة في فتحات التهوية؛

شهري: تنظيف الغبار من داخل المعدات (يجب أن يقوم بذلك فني متخصص).

6.1.2 طرق التنظيف

Wipe the exterior with a clean, soft, lint-free cloth; use a dedicated screen cleaner for the touchscreen; clean the vents with a soft-bristled brush and use a vacuum cleaner if necessary; do not use corrosive solvents such as acetone.

6.2 التفتيش الدوري

تحقق من سلك الطاقة بحثًا عن أي تلف أو تآكل؛ وتأكد من أن وصلة التأريض محكمة؛ وتأكد من أن المروحة تعمل بشكل طبيعي؛ وتأكد من استجابة الأزرار وشاشة اللمس؛ وتحقق من كتل التوصيل بحثًا عن أي أكسدة أو وصلات مفكوكة.

6.3.2 احتياطات التعامل

Unplug all external cables before moving the device; use the original packaging and ensure it is properly cushioned and protected; keep the device upright during transport and avoid harsh vibrations; when lifting, grip the bottom and sides of the device—do not lift by the panel.

6.4 متطلبات فترة المعايرة

لضمان دقة القياس وموثوقية تشغيل الجهاز، يُوصى بإرساله دوريًا إلى مختبر قياسات معتمد تابع لجهة خارجية لإجراء المعايرة. يُوصى بإجراء المعايرة كل 12 شهرًا. ويمكن للمستخدمين تحديد فترة المعايرة المناسبة بناءً على وتيرة الاستخدام والظروف البيئية ومتطلبات نظام الجودة.
