4. الإعداد

4.1 الشحن الأولي

Before first use, fully charge the device. Connect the provided USB Type-C cable to the HO52's charging port and the other end to the power adapter. Plug the adapter into a suitable power outlet. The charging indicator on the device will show the charging status. A full charge typically takes several hours.

4.2 Connecting Oscilloscope Probes

For oscilloscope measurements, connect the BNC end of the oscilloscope probe to either the CH1 or CH2 input connector on the top of the device. Ensure a secure connection by twisting the BNC connector until it locks. Attach the probe's ground clip to the circuit's ground point and the probe tip to the test point.

4.3 Connecting Multimeter Test Leads

For multimeter measurements, insert the red test lead into the VΩC+ port and the black test lead into the COM port. For current measurements, insert the red test lead into the mA port (for milliampere measurements) or the 10A port (if available on your model, for higher current measurements) and the black test lead into the COM port. Always ensure correct polarity and port selection for the measurement type.

5. تعليمات التشغيل

5.1 تشغيل/إيقاف التشغيل

اضغط مع الاستمرار على مفتاح تبديل الطاقة (usually located at the bottom left of the control panel) for a few seconds to turn the device on or off.

5.2 اختيار الوضع

اضغط على مفتاح الوضع to toggle between Oscilloscope mode and Multimeter mode. The display will change to reflect the active mode.

5.3 Oscilloscope Operation
