4. Setup
4.1 Initial Charging
Before first use, fully charge the oscilloscope's internal 2500mA battery using the provided USB cable and a standard 5V power adapter. The charging indicator will show the charging status.
4.2 Connecting Probes
- Ensure the oscilloscope is powered off.
- Connect the BNC connector of your probe (e.g., crocodile clip cable or high-voltage probe) to the desired input channel (CH1 or CH2) on the top of the oscilloscope.
- If using a high-voltage probe, ensure its attenuation setting (e.g., X1 or X10) matches the setting selected on the oscilloscope for accurate readings.
- Connect the ground clip of the probe to the ground reference of the circuit under test.
5. Operating Instructions
5.1 Powering On/Off
To power on the device, slide the OFF/ON switch to the 'ON' position. To power off, slide it to 'OFF'.
5.2 Basic Waveform Measurement (AUTO Function)
- Connect the probe to the circuit you wish to measure.
- Power on the oscilloscope.
- Press the Auto button. The oscilloscope will automatically adjust the vertical scale, time base, and trigger settings to display a stable waveform.
- Observe the waveform and measurement parameters on the screen.

5.3 Trigger Functions
The SCO2 offers three trigger modes:
- Auto: Automatically triggers and displays waveforms, even if the signal is not perfectly stable.
- Normal: Triggers only when the signal meets the set trigger conditions. Useful for stable display of periodic signals.
- Single: Captures a single event when the trigger conditions are met and then stops. Ideal for non-periodic or transient signals.
Access and adjust trigger settings via the Menu button.
5.4 Waveform Compression and Expansion
The oscilloscope supports waveform compression and expansion, allowing you to view long signal captures or zoom into specific details. With a 20K storage depth, waveforms can be compressed up to 165 times to observe changes over extended periods.
Use the + and - buttons, or navigate through the menu, to adjust the waveform display scale.
5.5 PC Software and Firmware Updates
The SCO2 supports PC software for system updates and future advanced functionalities like FTT (Fast Fourier Transform) and upper computer communication. Connect the oscilloscope to your computer via the USB port. Refer to the official SPORTARC website or contact customer service for the latest software and firmware updates (e.g., after September 1, 2023).
6. Maintenance
6.1 Cleaning
To clean the oscilloscope, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid using abrasive cleaners or solvents that could damage the casing or screen.
6.2 Storage
Store the oscilloscope in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Keep it protected from dust and physical impact. If storing for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.
6.3 Battery Care
The SCO2 is equipped with a rechargeable lithium battery. To maximize battery life:
- Avoid fully discharging the battery frequently.
- Do not expose the device to high temperatures.
- Charge the device regularly, even if not in frequent use.
7. Troubleshooting
Common Issues and Solutions:
- No Power: Ensure the battery is charged. Connect the USB cable to a 5V power source and check if the charging indicator lights up.
- No Waveform Display:
- Check probe connections to CH1/CH2 and the circuit under test.
- Ensure the ground clip is properly connected.
- Press the Auto button to automatically adjust settings.
- Verify the input signal is within the measurable voltage range (±40V for X1, ±400V for X10).
- Adjust the vertical scale (V/DIV) and time base (S/DIV) manually if Auto mode doesn't yield results.
- Unstable Waveform:
- Adjust the trigger level.
- Change the trigger mode (Auto, Normal, Single) to suit the signal type.
- Ensure the probe is securely connected and not picking up excessive noise.
- Incorrect Readings:
- Verify the probe attenuation setting (X1/X10) matches the oscilloscope's setting.
- Check for proper grounding.
