3. Installation

3.1 Chargement de l'appareil

1. Connect the provided USB cable to the oscilloscope's charging port.
2. Connectez l'autre extrémité du câble USB à un adaptateur secteur USB standard (non inclus) ou au port USB d'un ordinateur.
3. The charging indicator will illuminate. A full charge typically takes several hours and provides up to 8 hours of continuous operation.

3.2 Connexion de la sonde

1. Ensure the oscilloscope is powered off before connecting the probe.
2. Connect the BNC connector of the oscilloscope probe to the input BNC port on the oscilloscope.
3. Attach the ground clip of the probe to the ground point of the circuit under test.
4. Select the appropriate attenuation setting (1X or 10X) on the probe based on the expected signal voltage. For higher voltages, use 10X.
5. Important: When using the 10X attenuation setting on the probe, ensure the oscilloscope's input setting is also configured for 10X to obtain accurate readings. Failure to do so may result in incorrect measurements or potential damage if high voltage is applied with a 1X setting.

4. Mode d'emploi

4.1 Mise sous/hors tension

• Pour allumer l'appareil, maintenez le bouton d'alimentation enfoncé jusqu'à ce que l'écran s'allume.
• Pour éteindre l'appareil, maintenez le bouton d'alimentation enfoncé jusqu'à ce que l'écran s'éteigne.

4.2 Mesure automatique (AUTO)

The one-button AUTO function automatically adjusts the vertical, horizontal, and trigger settings to display a stable waveform. This is useful for quickly viewinterprétant un signal inconnu.

• Appuyez sur le AUTO button. The oscilloscope will attempt to automatically detect and display the input waveform.

4.3 Triggering Functions

Triggering stabilizes repetitive waveforms and captures single-shot events. Press the TRIGONOMÉTRIE bouton permettant d'accéder aux paramètres de déclenchement.

• Auto Trigger: The oscilloscope triggers automatically, even without a stable signal. Suitable for most general-purpose measurements.
• Normal Trigger: The oscilloscope triggers only when the signal meets the specified trigger conditions. If no trigger event occurs, the display remains unchanged. Useful for capturing specific events.
• Déclencheur unique : The oscilloscope waits for a single trigger event, captures one waveform, and then stops. Ideal for capturing non-repetitive or transient events.
• Bord de déclenchement : Utilisez le BORD button to select between rising edge or falling edge triggering.

4.4 Stockage et gestion des formes d'onde

The device allows for easy storage and management of waveform images.

• Enregistrer la forme d'onde : Appuyez sur le SAUVEGARDER button to instantly store the current waveform displayed on the screen. The device has 64M storage, capable of holding up to 2000 images.
• Waveform Manager: Access the waveform file manager through the MENU button. This allows for thumbnail browsing, viewing, detailed inspection, page turning, and deletion of stored waveforms.

4.5 Adjusting Display and Settings

• Sensibilité verticale (Volts/Div) : Use the up/down arrow buttons to adjust the vertical scale, changing the voltage represented by each vertical division on the grid.
• Base de temps horizontale (sec/div) : Use the left/right arrow buttons to adjust the horizontal scale, changing the time represented by each horizontal division on the grid.
• Couplage AC/DC : Appuyez sur le CA/CC button to toggle between AC and DC coupling. AC coupling blocks the DC component of the signal, showing only the AC variations. DC coupling shows the entire signal, including both AC and DC components.
• Luminosité de l'écran : Adjust screen brightness through the MENU réglages pour un fonctionnement optimal viewdans diverses conditions d'éclairage.

5. Entretien

5.1 Nettoyage

• Power off the device and disconnect all probes and cables before cleaning.
• Use a soft, dry cloth to wipe the exterior of the oscilloscope.
• Pour les saletés tenaces, appliquez légèrementampNettoyez le chiffon avec de l'eau ou un nettoyant doux non abrasif. Évitez d'utiliser des produits chimiques agressifs ou des solvants.
• Ne laissez aucun liquide pénétrer dans l'appareil.

5.2 Entretien de la batterie

• Pour prolonger la durée de vie de la batterie, évitez de la décharger complètement et fréquemment.
• If storing the device for an extended period, charge the battery to approximately 50% and store it in a cool, dry place. Recharge every few months to prevent deep discharge.
• Utilisez uniquement le câble USB fourni pour le chargement.

5.3 Stockage

• Rangez l'oscilloscope dans son étui de protection lorsqu'il n'est pas utilisé afin d'éviter tout dommage physique.
• Keep the device away from extreme temperatures, high humidity, and direct sunlight.
