6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Connect the device to a power source using the USB Type-C cable and charge it fully. |
| No waveform displayed in Oscilloscope mode. | Probe not connected correctly; incorrect trigger settings; signal too weak or out of range. | Ensure the probe is securely connected. Press AUTO button. Adjust vertical sensitivity and trigger level. Check signal source. |
| Waveform is unstable or noisy. | Improper grounding; external interference; incorrect time base or trigger settings. | Ensure proper grounding. Minimize external interference. Adjust time base and trigger settings. |
