5. Configuración

5.1 Conexión de alimentación

1. Connect the supplied power lead to the power input on the rear panel of the oscilloscope.
2. Plug the other end of the power lead into a grounded AC power outlet.
3. Presione el botón de encendido en el panel frontal para encender el osciloscopio.

5.2 Conexión de sonda

1. Connect the BNC connector of the passive probe to either Channel 1 (CH1) or Channel 2 (CH2) input on the front panel.
2. Conecte la pinza de tierra de la sonda al punto de tierra del circuito.
3. Connect the probe tip to the test point in your circuit.
4. Ensure the probe's attenuation setting (e.g., 1X or 10X) matches the setting on the oscilloscope for accurate readings.

6. Instrucciones de funcionamiento

6.1 Funcionamiento básico

• Auto Scale: Press the 'AUTO SET' button to automatically adjust vertical, horizontal, and trigger settings for a stable waveform display. This function detects sine and square waves automatically.
• Vertical Controls (VOLTS/DIV, POSITION): Use the VOLTS/DIV knobs to adjust the vertical scale (voltage per division) for each channel. The POSITION knobs shift the waveform vertically.
• Horizontal Controls (SEC/DIV, POSITION): Use the SEC/DIV knob to adjust the horizontal scale (time per division). The horizontal POSITION knob shifts the waveform horizontally.
• Nivel de disparo: Adjust the 'TRIGGER LEVEL' knob to set the voltage level at which the oscilloscope captures a waveform.

6.2 funciones avanzadas

• Generador de forma de onda: Access the waveform generator menu to select and configure output waveforms such as Sine, Square, Ramp, Exponential, Noise, and DC. Connect the 'WAVE GEN' output to your circuit.
• Modos de disparo: Utilize the 14 available trigger modes (Edge, Pulse, Video, Slope, Overtime, Window, Pattern, Interval, Under Amp, UART, LIN, CAN, SPI, IIC) to capture specific events. Select modes via the 'TRIGGER' menu.
• Decodificación del protocolo serie: The oscilloscope supports decoding for RS232/UART, I2C, SPI, CAN, and LIN protocols. Configure these settings in the 'DECODE' menu to view decoded data.
• Medidas: The device offers 32 types of automatic measurements with real-time statistics (maximum, minimum, standard deviation, etc.). Access these via the 'MEASURE' menu.
• Conectividad USB: Connect a USB thumb drive to the USB Host port to save oscilloscope setups, waveforms, reference waveforms, CSV files, and images. The USB Device port allows for remote control from a computer using SCPI commands.

7. Mantenimiento

7.1 Limpieza

Para limpiar el instrumento, utilice un paño suave.ampLimpie con una solución de detergente suave. No utilice limpiadores abrasivos ni disolventes que puedan dañar el...asing o pantalla. Asegúrese de que el dispositivo esté apagado y desenchufado antes de limpiarlo.

7.2 Almacenamiento
