Connecting Test Leads
Insert the red test lead into the "INPUT" or "VΩ" jack and the black test lead into the "COM" jack for most measurements. For current measurements, use the "10A FUSED" or "6A" jack for the red lead, depending on the expected current range.
Operating Instructions
General Operation
The device features a 2.8-inch color TFT screen for clear display of measurements and waveforms. Use the navigation buttons (up, down, left, right) and the 'AUTO' and 'FUNC' buttons to navigate menus and select modes.

Multimeter Mode
In Multimeter Mode, the device functions as a true RMS digital multimeter. It can measure a variety of electrical parameters:
- Voltage: AC and DC voltage measurement.
- Current: AC and DC current measurement (up to 10A).
- Resistance: Measures electrical resistance.
- Capacitance: Measures capacitance values.
- Diode: Tests diodes within 3V.
- Continuity: Checks for circuit continuity with an audible alert.
- V-Alert (Non-Contact Voltage Detection): Detects AC voltage without direct contact.
- Live Wire Check: Identifies live wires.
- MAX/MIN/AVG: Displays maximum, minimum, and average values during measurements.
To switch between measurement functions within Multimeter Mode, press the FUNC button. The AUTO button enables auto-ranging for most measurements.
Oscilloscope Mode
The Oscilloscope Mode allows for waveform visualization and analysis. Key features include:
- Bandwidth: 10MHz.
- Real-time Sample Rate: 48MSa/s.
- Auto-Calibration: Ensures accurate readings.
- Memory Function: Stores waveform data.
- Horizontal SEC Range: 100ns/div - 20s/div.
- Vertical Sensitivity: 20mV/div - 100V/div.
Use the navigation buttons to adjust the time base, voltage division, and trigger settings. The AUTO button can automatically set optimal display parameters for the input signal.

Maintenance
Battery Care
The device uses a rechargeable Lithium Ion battery. To ensure optimal battery life, charge the device regularly and avoid fully discharging it for extended periods. Always use the provided charging cable.
Cleaning and Storage
Clean the device with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Store the multimeter in its provided carrying case to protect it from dust, moisture, and physical damage when not in use.
Serviceability
The device is designed for serviceability. The case uses screws, and components such as the fuse and LiPo battery can be replaced without desoldering, if necessary. For complex repairs, it is recommended to contact qualified service personnel.
Troubleshooting
If you encounter issues with your BSIDE O1 Green, consider the following common troubleshooting steps:
- Device not powering on: Ensure the battery is charged. Connect the charging cable and allow it to charge for at least 30 minutes before attempting to power on again.
- Inaccurate readings: Check that the test leads are properly connected to the correct jacks for the measurement type. Ensure the probes are making good contact with the circuit. Perform an auto-calibration if available in the device settings.
- Display issues: If the screen is dim or unreadable, adjust the brightness settings. If the display is frozen, try restarting the device.
- No waveform displayed in Oscilloscope Mode: Verify that the input signal is within the device's bandwidth and voltage range. Adjust the time base and vertical sensitivity settings. Ensure the trigger is set appropriately.
For persistent issues, refer to the detailed user manual included in the package or contact BSIDE customer support.
