9. Entretien

10. Dépannage

ProblèmeCause possibleSolution
L'appareil ne s'allume pas.Batterie faible ou déchargée.Connect the device to a power source using the USB Type-C cable and allow it to charge.
Aucune forme d'onde n'est affichée en mode oscilloscope.Probe not connected correctly; signal too small or too large; incorrect time base or voltage échelle.Ensure probe is securely connected. Press Auto for automatic setup. Adjust vertical and horizontal scales manually. Check trigger settings.
Les mesures du multimètre sont inexactes.Test leads not properly connected; incorrect measurement function selected; external interference.Verify test lead connections. Ensure the correct measurement mode (voltage, current, resistance) is selected. Minimize external electrical noise.
Le signal de sortie du générateur n'est pas conforme aux attentes.Incorrect waveform type, frequency, or amplitude set.Vérifiez la forme d'onde, la fréquence et ampParamètres d'altitude dans le menu du générateur de signal.
