5. Istruzioni per l'uso

The DSO-2202H + AFG offers three primary modes of operation: Oscilloscope, Multimeter, and Arbitrary Function Generator.

5.1 Modalità oscilloscopio

This mode allows you to visualize and analyze electrical signals. The device features 2 channels and a 200MHz bandwidth.

1. Premere il tasto Modalità pulsante per selezionare la modalità Oscilloscopio.
2. Connect the oscilloscope probe(s) to the circuit under test.
3. Utilizzare il CH1/2 button to switch between channels or view Entrambi.
4. Adjust the vertical sensitivity (V/div) and horizontal time base (s/div) using the navigation buttons.
5. Utilizzare il Trigonometria/Δ button to set trigger conditions for stable waveform display.
6. IL Auto button can automatically adjust settings for a stable waveform.

5.2 Modalità multimetro

The multimeter function allows for precise measurements of voltage, corrente, resistenza, capacità e continuità.

1. Premere il tasto Modalità pulsante per selezionare la modalità Multimetro.
2. Connect the test leads to the appropriate input jacks (e.g., VΩ+C for voltage/resistance/capacitance, A or mA for current, COM for common).
3. Select the desired measurement function (e.g., DC Voltage, AC voltage, Resistance) using the function buttons (F1-F4) or navigation keys.
4. Leggere il valore della misurazione sul display.

5.3 Arbitrary Function Generator (AFG) Mode

L'AFG consente di generare varie forme d'onda per testare i circuiti.

1. Premere il tasto Modalità button to select AFG mode.
2. Connect the output of the AFG to the circuit requiring a signal input.
3. Use the function buttons (F1-F4) and navigation keys to select waveform type (sine, square, triangle, etc.), frequency, amplitude e offset.
4. Adjust parameters as needed for your application.

5.4 Conservazione dei dati

The USB Type-C port can be used for data storage. Connect the device to a computer using a USB Type-C cable to transfer saved waveforms or measurement data.

6. Manutenzione

Una corretta manutenzione garantisce la longevità e la precisione del tuo dispositivo.

• Pulizia: Pulire regolarmente il dispositivo con un panno morbido e asciutto. Non utilizzare detergenti abrasivi o solventi.
• Magazzinaggio: Conservare il dispositivo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
• Cura della batteria: If the device has an internal rechargeable battery, ensure it is charged periodically if stored for long periods to maintain battery health.
• Cura della sonda: Inspect probes and test leads for damage before each use. Replace any damaged accessories immediately.

7. Risoluzione Dei Problemi

If you encounter issues with your device, refer to the following common troubleshooting steps.

• Il dispositivo non si accende: Ensure the device is charged or connected to a power source. Check the power button for proper engagement.
• Nessuna visualizzazione: If the device powers on but the screen is blank, try adjusting the display brightness (if available) or restarting the device.
• Letture errate: Verify that probes and test leads are correctly connected and not damaged. Ensure the correct measurement mode and range are selected. Calibrate the device if necessary (refer to advanced settings or contact support).
• Forma d'onda instabile: In oscilloscope mode, adjust the trigger level, trigger source, and time base settings. Use the Auto button for initial setup.
