9. User Tips
- Probe Calibration: For accurate measurements, especially with 10X probes, ensure your probes are properly compensated. Most oscilloscopes have a square wave output for this purpose.
- Grounding: Always ensure proper grounding of your oscilloscope and the circuit under test to avoid noise and ensure safety.
- Start Simple: When troubleshooting a circuit, start with simple signals (like a sine wave from the built-in generator) to verify the oscilloscope's functionality before moving to complex signals.
- Screen Protector: While the screen is resistive touch, a screen protector can help prevent scratches during field use.
