3. Instrucións de funcionamento
3.1. Acendido/apagado
Prema o botón de acendido do panel frontal para acender ou apagar o osciloscopio.
3.2. Visualización básica de formas de onda
After powering on, connect a signal to CH1 or CH2. Use the Vertical (Position and Scale) and Horizontal (Position and Scale) knobs to adjust the waveform's position and size on the screen. The oscilloscope features a 110MHz bandwidth and 1GSa/s real-time sampling rate for accurate signal capture.
3.3. Triggering
The Trigger section allows you to stabilize repetitive waveforms. Adjust the Trigger Level knob to set the voltage threshold at which the oscilloscope starts acquiring data. Use the Trigger Menu button to access advanced trigger settings.
3.4. Medicións
Press the 'Measure' button to access automatic measurement functions. The oscilloscope can display various parameters such as frequency, peak-to-peak voltage, RMS voltage, e máis.
3.5. Almacenamento de datos
The USB Host interface on the front panel allows you to save waveform data, screenshots, and settings to a USB flash drive. The storage depth for acquired waveforms is not less than 10K samppuntos ling.
4. Mantemento
4.1. Limpeza
To clean the oscilloscope, use a soft, dry cloth. For stubborn dirt, a cloth lightly dampened with water or a mild cleaning solution can be used. Avoid using abrasive cleaners or solvents that could damage the casing or screen. Ensure the device is powered off and unplugged before cleaning.
4.2. Almacenamento
Store the oscilloscope in a clean, dry environment away from direct sunlight, extreme temperatures, and high humidity. When not in use for extended periods, disconnect all probes and power cables.
5 Solución de problemas
- Sen enerxía: Ensure the power cord is securely connected to both the oscilloscope and the power outlet. Check the power button.
- No Waveform Display: Verify that the input signal is connected correctly to CH1 or CH2. Adjust the Vertical Scale (V/div) and Horizontal Scale (s/div) knobs to bring the waveform into view. Check the trigger settings.
- Unstable Waveform: Adjust the Trigger Level and Trigger Mode settings to stabilize the waveform. Ensure the trigger source is correctly selected.
- Incorrect Measurements: Calibrate probes if necessary. Ensure the input coupling (AC/DC) is appropriate for the signal being measured.
- Mal funcionamento do dispositivo: If the oscilloscope does not function correctly upon receipt, contact customer support for immediate assistance. The manufacturer offers replacement for new items at once for such issues.
