3. Configuración
3.1 Carga del dispositivo
Before initial use, fully charge the device using the provided USB Type-C cable and a compatible power adapter (not included). The charging indicator on the device will show the charging status.
3.2 Conexión de sondas y cables
- Sondas de osciloscopio: Connect the BNC connector of the oscilloscope probes to the CH1 and CH2 input ports on the top of the device. Ensure a secure connection.
- Cables de prueba del multímetro: For multimeter functions, insert the red test lead into the VΩ+C jack and the black test lead into the COM jack. For current measurements, use the A or mA jacks as appropriate.
3.3 Encendido / Apagado
Mantenga pulsado el Fuerza button (usually marked with a circle and vertical line symbol) to turn the device on or off.
4. Instrucciones de funcionamiento
4.1 Navegación general
- Utilice el Modo button to switch between Oscilloscope and Multimeter modes.
- The directional pad (up, down, left, right) is used to navigate menus and adjust parameters.
- Botones F1 a F4 correspond to on-screen menu options.
- El Sistema button accesses system settings.
- El Ahorrar button allows saving waveforms or measurement data.
4.2 Modo de osciloscopio
In Oscilloscope mode, the device displays real-time waveforms. Use the following controls:
- CH1/2: Selects the active channel or displays both.
- HOR (Horizontal): Adjusts the time base (horizontal scale) of the waveform.
- Escala vertical: Use the directional pad (up/down) to adjust the voltage scale for the selected channel.
- Trig/Δ (Trigger): Configures trigger settings (edge, level, mode) to stabilize the waveform display.
- Auto: Automatically adjusts vertical, horizontal, and trigger settings for a stable waveform display.
- Reproducir/Pausa: Freezes or resumes the waveform acquisition.
4.3 Modo multímetro
In Multimeter mode, the device functions as a digital multimeter. Use the directional pad to select the desired measurement function (Voltage, Current, Resistance, etc.). Ensure the test leads are connected to the correct input jacks for the selected measurement type.
- Volumentage Medida (V): Conecte los cables en paralelo con el circuito.
- Current Measurement (A/mA): Connect leads in series with the circuit. Ensure correct jack selection (A or mA) based on expected current.
- Medición de resistencia (Ω): Connect leads across the component when power is off.
- Continuidad/Diodo: For checking circuit continuity or diode function.
- Medición de capacitancia (F): Connect leads across the capacitor when power is off.
