Important Notes
- Use the instrument within its normal operating environment.
- Select the correct working mode based on your needs.
- Ensure the input signal matches impedance requirements; use impedance transformation for high internal resistance signals.
- For high-voltage signals, prioritize safety and avoid using these for instrument settings.
- Avoid direct contact with the crystal oscillator and chip to prevent static damage.
