4. Setup
4.1 Initial Charging
Before first use, fully charge the device using the provided charging cable. Connect the charging cable to the device's charging port and a standard USB power adapter (not included). The battery indicator on the screen will show charging status.

Figure 4.1: The BSIDE O7 is equipped with a 5000mAh rechargeable battery.
4.2 Connecting Probes and Leads
The BSIDE O7 features dedicated input ports for oscilloscope probes (CH1, CH2) and multimeter test leads (Input, COM). Ensure correct connection for accurate measurements.
- For oscilloscope functions, connect the oscilloscope probe to the CH1 or CH2 BNC ports.
- For multimeter functions, insert the red test lead into the "Input" jack and the black test lead into the "COM" jack.

5. Operating Instructions
The BSIDE O7 offers three primary operating modes: Oscilloscope, Multimeter, and DDS Signal Generator. Use the MODE button to switch between these functions.

Figure 5.0: The BSIDE O7 combines Multimeter, DDS Generator, and Oscilloscope functions.
5.1 Oscilloscope Mode
In Oscilloscope mode, the device displays waveforms, allowing for analysis of electrical signals. Connect the oscilloscope probe to the desired channel (CH1 or CH2).
- Press MODE to select Oscilloscope.
- Use the navigation buttons to adjust vertical sensitivity (Volts/Div) and horizontal time base (Time/Div).
- The TRIGGER function allows stable display of repetitive waveforms.
- Use CURSOR MEASURE for precise voltage and time measurements on the waveform.

5.2 Multimeter Mode
The Multimeter mode allows for standard electrical measurements such as voltage, current, resistance, capacitance, and temperature. Connect the test leads to the appropriate input jacks.
- Press MODE to cycle to Multimeter mode.
- Use the function buttons (e.g., V, A, Ω, CAP, TEMP) to select the desired measurement type.
- The device supports True RMS for AC measurements.
- For flexible AC current clamp measurements (up to 6000A), an external clamp is required (not included).
5.3 DDS Signal Generator Mode
The DDS (Direct Digital Synthesis) Generator mode allows the device to output various waveforms for testing circuits. The output is available via the "OUT" port.
- Press MODE to select DDS Generator mode.
- Select the desired waveform type (sine, square, triangle, full wave, half wave, sawtooth, DC wave) using the navigation buttons.
- Adjust frequency (0-2MHz) and output amplitude (0.1-3V) as needed.
- For square waves, the duty cycle can be adjusted from 1% to 99%.
6. Maintenance
6.1 Cleaning
To clean the device, use a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from any power source or test circuits before cleaning.
6.2 Battery Care
The device uses a rechargeable Li-ion battery. To prolong battery life:
- Avoid fully discharging the battery frequently.
- Charge the device regularly, even if not in use, to maintain battery health.
- Store the device in a cool, dry place if not used for extended periods.
6.3 Storage
When not in use, store the BSIDE O7 in its provided carrying case to protect it from dust, moisture, and physical damage. Keep it away from extreme temperatures and direct sunlight.
