9. Safety Precautions & Troubleshooting

Adhere to the following precautions to ensure safe operation and prevent damage to the device or injury.

1. Voltage Measurement: When measuring voltages exceeding 40V, always switch the probe position to X10.
2. High Voltage Handling: When measuring high voltage (more than 36V AC voltage), avoid touching any metal parts of the instrument, especially the BNC interface.
3. Charging Voltage: The charging voltage must not exceed 6.8V. Exceeding this limit can burn out the charging chip.
4. Mains Power Connection: When measuring mains power, it is strictly forbidden to connect the oscilloscope to a computer. This can cause a short circuit between the neutral wire and the ground, posing a severe safety risk.

Troubleshooting

• Device not powering on: Ensure the device is fully charged. Check the USB cable and power adapter.
• Unstable waveform display: Use the 'Auto' button to automatically adjust settings. Check probe connections and ensure proper grounding. Adjust trigger settings if necessary.
• Inaccurate readings: Verify probe attenuation settings (X1/X10) match the probe in use. Ensure proper calibration if available.

10. Care and Maintenance

• Keep the device clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
• Store the oscilloscope in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid dropping or subjecting the device to strong impacts.
• Regularly check probes and cables for any signs of wear or damage. Replace if necessary.
• Firmware upgrades are supported; refer to the manufacturer's website for the latest updates and instructions.

11. Warranty and Support
