4. الإعداد

4.1 تركيب البطارية وشحنها

1. حدد مكان حجرة البطارية في الجزء الخلفي من الجهاز.
2. Insert the provided Li-ion battery (7.4V) into the compartment, ensuring correct polarity.
3. أغلق غطاء حجرة البطارية جيدًا.
4. Connect the power adapter to the device's charging port and plug it into a suitable AC outlet (100V-240V AC, 50/60Hz). The battery indicator will show charging status.
5. Allow the device to charge fully before initial use. A full charge provides approximately 6 hours of operation.

4.2 توصيل المجسات وأسلاك الاختبار

• Oscilloscope Probe: For oscilloscope functions, connect the BNC connector of the oscilloscope probe to the BNC input port on the device. Ensure the probe's attenuation setting (e.g., 1X or 10X) matches the setting on the oscilloscope menu.
• أسلاك اختبار جهاز القياس المتعدد: For multimeter functions, insert the red test lead into the VΩmA input jack and the black test lead into the COM input jack. For high current measurements (e.g., 20A), use the dedicated current input jack if available and switch the function accordingly.

5. تعليمات التشغيل

5.1 تشغيل/إيقاف التشغيل

Press and hold the power button until the display illuminates to turn on the device. To power off, press and hold the power button again until the display shuts down.
