5. Operating Instructions
5.1 Basic Waveform Display
After powering on and connecting probes, the oscilloscope will display the input signal. Use the navigation buttons (Left, Right, +, -) to adjust horizontal (time base) and vertical (voltage scale) settings. The Auto button can automatically adjust these settings for a stable waveform display.

5.2 One-Button Automatic Measurement
Press the Auto button to automatically adjust the oscilloscope's settings (time base, voltage scale, trigger level) to display a stable waveform. This feature simplifies initial setup and quick signal viewing.
5.3 Cursor Measurement Function
The cursor measurement function allows for precise manual measurement of waveform parameters. Access this function via the Menu button. Use the navigation buttons to position the cursors and read out values for period, frequency, voltage, and other parameters displayed on the screen.
5.4 Built-in DDS Signal Generator
The oscilloscope includes a Direct Digital Synthesis (DDS) signal generator. To use it, connect the OUT port to the circuit you wish to test. Access the signal generator settings through the Menu to select waveform type (e.g., sine, square, triangle), frequency, and amplitude.
5.5 Saving Waveforms and Screenshots
The device has 1GB of built-in storage. To save the current waveform or screen display, press the OK/Hold button. Follow the on-screen prompts to save the data. Saved data can be reviewed later or transferred to a computer.
5.6 Connecting to a Computer (USB)
Connect the oscilloscope to a computer using the provided USB cable. This allows for data transfer, secondary analysis of saved waveforms, and potentially firmware updates. Refer to the specific software instructions for your operating system.
5.7 FFT Display Function
The Fast Fourier Transform (FFT) display function allows you to analyze the frequency components of a signal. Access this mode via the Menu. This is useful for identifying harmonics, noise, and other frequency-domain characteristics of your signal.
5.8 Adjusting Screen Brightness
You can adjust the screen brightness and background grid brightness through the device's menu settings to suit your viewing environment.
6. Maintenance
6.1 Cleaning
To clean the device, power it off and disconnect all probes and cables. Use a soft, dry cloth to wipe the exterior. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device. Do not use abrasive cleaners or solvents.
6.2 Storage
When not in use, store the oscilloscope in a cool, dry place, away from direct sunlight and extreme temperatures. Protect it from dust and physical impact. It is recommended to store it in its original packaging or a protective case.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or power cable not connected. | Charge the battery or connect the USB power cable. Ensure the power button is pressed correctly. |
| No waveform displayed. | Probe not connected, signal too small/large, or incorrect settings. | Check probe connections. Use the Auto button. Adjust vertical (Volts/Div) and horizontal (Time/Div) scales. Verify trigger settings. |
| Unstable waveform. | Incorrect trigger settings. | Adjust the trigger level and trigger mode (e.g., Edge, Auto). Use the Auto button. |
| Screen is too dim/bright. | Screen brightness settings. | Adjust screen brightness through the device's menu. |
