- Vertical Scale/Position: Adjust the vertical scale (Volts/div) and position to bring the waveform into view.
- Time Base: Adjust the time base (Sec/div) to capture the signal's frequency.
- Trigger Settings: Ensure trigger settings (level, mode, source) are correctly configured. Try 'Auto' trigger mode or 'Waveform Auto Display' function.
- Signal Source: Verify that the signal source is active and producing a signal.
7.3 Unresponsive Touchscreen
- Restart Device: Try restarting the oscilloscope.

8. User Tips
- Probe Compensation: Always compensate your probes before making critical measurements. This ensures accurate signal representation.
- Grounding: Proper grounding is crucial for accurate and safe measurements. Ensure your oscilloscope and the circuit under test share a common ground.
- Start with Auto-Set: If you're unsure about initial settings, use the 'Waveform Auto Display' function to quickly get a visible waveform, then fine-tune manually.
- Utilize Memory Depth: For capturing long, complex signals or transient events, maximize the memory depth to retain more waveform details.
- Explore Trigger Options: Experiment with different trigger types (Edge, Pulse, Runt, Slope, Zone) to stabilize specific parts of your waveform for analysis.
- SCPI Commands: For repetitive tasks or integration into automated test systems, leverage the SCPI remote command control for efficient operation.
- Regular Software Updates: Check the Hantek website for any firmware or software updates to ensure you have the latest features and bug fixes.
