5. Troubleshooting
If you encounter issues with your BSIDE O2, consider the following general troubleshooting steps:
- Device not powering on: Ensure the battery is sufficiently charged. Connect the device to a power source using the Type-C cable and try again.
- No waveform display: Check that probes are correctly connected to both the device and the circuit under test. Verify that the input signal is within the device's measurement range.
- Inaccurate readings: Ensure probes are properly calibrated (if applicable) and that the correct probe attenuation (1x/10x) is selected on both the probe and the device.
- Touch screen unresponsive: Restart the device. If the issue persists, ensure the screen is clean and free of debris.
- Connectivity issues with PC: Ensure the USB Type-C cable is securely connected. Try a different USB port or cable.
For persistent issues, refer to the detailed troubleshooting section in the full product manual (if available) or contact BSIDE customer support.
