5. Setup and Initial Use
5.1 Charging the Device
The BSIDE OS1 is equipped with a 1200mAh rechargeable battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB-C cable.
- Connect the USB-C end of the charging cable to the device's USB-C port.
- Connect the other end of the charging cable to a standard USB power adapter (not included) or a computer's USB port.
- The charging indicator on the screen will show the charging status.

5.2 Connecting Test Leads
The device uses standard test leads for all measurements, eliminating the need for separate BNC connectors.
- Insert the red test lead into the VΩHz input jack.
- Insert the black test lead into the COM (common) input jack.
- For oscilloscope measurements, the test leads are connected to the OSC input.

6. Operating Instructions
6.1 Power On/Off
- To power on: Press and hold the Power button (usually located on the side or top).
- To power off: Press and hold the Power button again until the screen turns off.
6.2 Switching Modes (Oscilloscope / Multimeter)
Press the MODE button to toggle between Oscilloscope mode and Multimeter mode.

Figure 6.1: Multimeter and Oscilloscope modes.
6.3 Oscilloscope Mode
In Oscilloscope mode, the device displays waveforms, allowing for analysis of signal characteristics such as frequency, amplitude, and period.

Figure 6.2: Oscilloscope mode in use.
6.3.1 Trigger Functions
The OS1 supports Auto, Normal, and Single trigger modes:
- Auto Trigger: Automatically triggers when a signal is present.
- Normal Trigger: Triggers only when the signal meets the set trigger conditions.
- Single Trigger: Captures a single waveform when the trigger condition is met, then stops.
Use the Function Wheel to adjust trigger level and type.
6.3.2 Time Base and Vertical Sensitivity
Adjust the horizontal (time base) and vertical (voltage sensitivity) scales using the Function Wheel to properly view and analyze waveforms.
6.4 Multimeter Mode
In Multimeter mode, the device performs various electrical measurements with a 6000-count display.
6.4.1 Measurement Functions
Use the Function Wheel to select the desired measurement type:
- DC/AC Voltage: Measures direct and alternating current voltage.
- Resistance: Measures electrical resistance in Ohms (Ω).
- Capacitance: Measures capacitance in Farads (F).
- Diode Test: Checks the functionality of diodes.
- Continuity Test: Checks for electrical continuity with an audible buzzer.
- MAX/MIN/AVG: Displays maximum, minimum, and average readings.
6.5 Data Saving and Export
The BSIDE OS1 allows for saving tested data. Refer to the on-screen menu options for saving measurements and waveforms. Data can be exported to a computer via the USB-C connection for further analysis (specific software or driver may be required, refer to manufacturer's website for details).
7. Maintenance
7.1 Cleaning
To clean the device, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or screen.

8. Troubleshooting
If you encounter issues with your BSIDE OS1, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery | Charge the device fully. |
| No reading in Multimeter mode | Incorrect test lead connection or wrong mode selected | Ensure test leads are properly connected and the correct measurement function is selected. Check the circuit. |
| Unstable waveform in Oscilloscope mode | Incorrect trigger settings or time base/vertical sensitivity | Adjust trigger level, type (Auto/Normal/Single), time base, and vertical sensitivity. |
| Screen is blank or frozen | Software glitch | Perform a hard reset by holding the power button for an extended period (e.g., 10-15 seconds) or allow the battery to fully discharge and then recharge. |
