4. Setup

4.1 Initial Charge

Before first use, fully charge the oscilloscope using the provided USB Type-C cable and a compatible power adapter (not included). The charging indicator will show progress.

4.2 Attaching Probes

Connect the oscilloscope probes to the BNC connectors labeled "OSC 1" and "OSC 2" on the top of the device. Ensure a secure connection by twisting the probe connector until it locks into place.

4.3 Powering On/Off

Press and hold the power button located on the side of the device to power on or power off the oscilloscope. A short press will typically toggle the screen or enter/exit standby mode.

5. Operating Instructions

This section details the primary functions and modes of the O2 Digital Oscilloscope.

5.1 Basic Operation and Navigation

The device features a touchscreen interface for most operations. Use the function wheel on the side for fine adjustments or menu navigation where applicable.

5.2 Oscilloscope Mode

The oscilloscope mode allows for real-time waveform display and analysis.

• Automatic Measurement: Press the AUTO button for one-button automatic setting of all parameters to display measured waveforms. Long press the AUTO button to quickly calibrate the baseline.
• Trigger Function: Utilize the full trigger function (Auto/Normal/Single) to capture specific waveform events.
• Vertical Sensitivity: Adjust the vertical sensitivity (20mV/div-10V/div) to scale the waveform vertically.
• Horizontal Sampling Rate: Adjust the horizontal sampling rate (1.5Sa/s-250MSa/s) to control the time base.
• Display Mode: Switch between XT, XY, and Scroll display modes as needed for different analysis requirements.
• Afterglow Time: Configure the afterglow time (min, 500ms, 1s, 10s, unlimited) to observe waveform persistence.

5.3 Signal Generator Mode

The built-in signal generator can output various waveforms.

• Waveform Types: Generate Sine, Square, Triangle, Half, Full, Ramp, and DC waveforms.
• Frequency Range: Set the frequency from 0Hz to 2MHz.
• Output Amplitude: Adjust the output amplitude from 0.1V to 3.0V.
• Square Wave Duty Cycle: For square waves, adjust the duty cycle from 1% to 99%.

5.4 Data Storage and Export

The oscilloscope supports storing previewed data and exporting it for further analysis.

6. Maintenance

6.1 Cleaning

To clean the device, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild soap can be used, ensuring no liquid enters the device openings. Do not use abrasive cleaners or solvents.

6.2 Storage

When not in use, store the oscilloscope in its EVA storage bag to protect it from dust, moisture, and physical damage. Store in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your O2 Digital Oscilloscope, refer to the following common problems and solutions:

• Device does not power on:
  • Ensure the battery is sufficiently charged. Connect the device to a power source using the USB Type-C cable.
  • Press and hold the power button for at least 3 seconds.
• No waveform displayed:
  • Check if probes are securely connected to the BNC inputs.
  • Verify that the input signal is within the device's measurement range.
  • Press the AUTO button to automatically adjust settings.
  • Ensure the correct channel (CH1 or CH2) is enabled on the display.
• Waveform is unstable or noisy:
  • Check probe connections for looseness.
  • Ensure proper grounding of the circuit being tested.
  • Adjust the trigger settings (level, mode) to stabilize the waveform.
  • Consider the probe attenuation setting (x1 or x10) and ensure it matches the device setting.
• Touchscreen is unresponsive:
  • Restart the device by powering it off and on again.
  • Ensure the screen is clean and free of debris.

If the issue persists after attempting these solutions, please contact customer support.
