4. Maintenance
4.1. Cleaning
To clean the oscilloscope, use a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or screen. Ensure the device is powered off and unplugged before cleaning.
4.2. Safety Warnings
WARNING: Hazardous voltage inside. Do not remove the cover unless by specified personnel. Refer to the warning labels on the rear panel of the device (Figure 5).
4.3. Calibration
For optimal performance, periodic calibration by qualified personnel is recommended. Refer to the official Hantek support resources for information on calibration services.
5. Troubleshooting
If you encounter issues with your oscilloscope, try the following basic troubleshooting steps:
- No Power: Ensure the power cable is securely connected and the power outlet is functional. Check the power button.
- No Signal Display: Verify that probes are correctly connected to the input channels and the signal source. Check probe settings (1X/10X) and vertical sensitivity.
- Unstable Waveform: Adjust the trigger level and trigger mode. Ensure the time base is appropriate for the signal frequency.
- Incorrect Readings: Perform a self-calibration if available in the utility menu. Check probe compensation.
For more complex issues, consult the comprehensive user manual (if a PDF version is available, it would be referenced here) or contact Hantek technical support.
