5. Setup

5.1 Charging the Device

Before first use, ensure the oscilloscope is fully charged. Connect the provided charging cable to the charging port on the device and to a standard 5V USB power adapter (not included). The built-in 2500mAh Li-Battery provides approximately 4.5-6 hours of continuous working time when fully charged.

5.2 Connecting Probes

1. Identify the two red and black probe clips.
2. Connect the BNC connector of each probe clip to the CH1 and CH2 input ports on the top of the oscilloscope.
3. Ensure the connections are secure.

6. Operating Instructions

6.1 Power On/Off

To power on the oscilloscope, slide the OFF/ON switch to the 'ON' position. To power off, slide it to the 'OFF' position.

6.2 Basic Waveform Display

1. Connect the probe clips to the circuit you wish to measure. Remember to connect the ground clip first.
2. Press the Auto button to automatically adjust the vertical and horizontal scales for a stable waveform display.
3. Use the + and - buttons to manually adjust the voltage scale (V/DIV) or time base (S/DIV) as needed.
4. The Left and Right buttons can be used to shift the waveform horizontally.

8. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents.
• Storage: Store the oscilloscope in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in use for extended periods.
• Probe Care: Inspect probe clips regularly for damage. Replace if insulation is compromised.

9. Troubleshooting

• Device does not power on:
  • Ensure the battery is charged. Connect the charging cable and try again.
  • Verify the OFF/ON switch is in the 'ON' position.
• No waveform displayed:
  • Check if probes are correctly connected to the input channels and the circuit under test.
  • Press the Auto button to automatically adjust the display settings.
  • Ensure the input signal is within the voltage measurement range of the oscilloscope.
• Waveform is unstable or noisy:
  • Ensure proper grounding of the probe and the circuit.
  • Adjust the time base and voltage scale using the + and - buttons.
  • Minimize external electromagnetic interference.
