• Durada del registre: With a record length of 10K, the oscilloscope can capture and store detailed waveform data.
• Saving Waveforms: Use the 'Function' menu, select 'Save', and choose the desired type (e.g., 'Image' or 'Data') to store waveforms to a USB drive.
• PC Communication: Connect the oscilloscope to a host computer via the USB interface for advanced data analysis, remote control, and waveform storage using the provided software.

7. Manteniment

• Neteja: Use a soft, dry cloth to clean the exterior of the oscilloscope. For stubborn dirt, a slightly damp Es pot fer servir un drap amb detergent suau, assegurant-se que no entri líquid al dispositiu.
• Emmagatzematge: Store the oscilloscope in a cool, dry environment, away from direct sunlight and extreme temperatures.
• Cura de la sonda: Handle probes carefully. Avoid bending or twisting the cables excessively. Regularly check for damage to the probe tips and connectors.

8. Solució De Problemes

• Sense energia: Check the power cable connection and the power outlet. Ensure the power adapter is functioning correctly.
• Sense visualització de forma d'ona: Verify that probes are correctly connected to both the oscilloscope and the circuit under test. Check the input channel selection (CH1/CH2) and ensure the vertical scale is appropriate for the signal amplitude. Try the 'Autoset' function.
• Forma d'ona inestable: Adjust the trigger level and trigger mode. Ensure the trigger source is correctly selected. Check for noise in the signal path.
• Mesures incorrectes: Ensure probes are properly compensated (if applicable) and that the probe attenuation setting on the oscilloscope matches the physical probe (e.g., 1X, 10X).
