Store the equipment in a cool, dry, and dust-free environment, away from direct sunlight, heat, moisture, or vibration. Additionally, follow the manufacturer's instructions and safety precautions when using the equipment; do not exceed the rated voltage, current, or power limits. It is also recommended to update the firmware or software of your equipment regularly for optimal performance and compatibility. By doing this, you can ensure that your oscilloscope and function generator equipment are properly calibrated and maintained for accurate and reliable electrical testing results.
