5. Setup
5.1. Charging the Battery
The BSIDE A1X Multimeter comes with a built-in 400mAh lithium-ion battery. Before first use, or when the battery is low, charge the device using the provided Type-C cable.
- Locate the Type-C charging port on the side of the multimeter.
- Connect the Type-C cable to the multimeter and the other end to a compatible USB power source (e.g., computer, USB wall adapter).
- The device will indicate charging status (e.g., an indicator light).
5.2. Initial Power-On
Press and hold the power button (usually marked with a power symbol) to turn on the multimeter. The LCD display will light up, and the device will typically enter auto-identification mode.

6. Operating Modes
The BSIDE A1X features intelligent identification, automatically selecting the appropriate measurement mode for most tasks. You can also manually select specific functions using the function buttons.
6.1. Voltage Measurement (AC/DC)
- Connect the red test lead to the 'INPUT' terminal and the black test lead to the 'COM' terminal.
- Touch the probes to the points where you want to measure voltage. The multimeter will automatically detect AC or DC voltage and display the reading.
6.2. Resistance and Continuity Test
- Connect the test leads as described for voltage measurement.
- Touch the probes to the component or circuit you wish to test. The multimeter will display the resistance value.
- For continuity, if the resistance is less than 50Ω, the buzzer will sound, indicating continuity.
6.3. Capacitance and Diode Test
- Connect the test leads as described for voltage measurement.
- Press the function button to cycle through modes until the capacitance or diode symbol is displayed.
- Touch the probes to the capacitor or diode. The multimeter will display the capacitance value or diode forward voltage drop.
6.4. NCV (Non-Contact Voltage) Detection
- Hold the multimeter near the wire or electrical outlet. The NCV sensor is located at the top of the device.
- If AC voltage is detected, the device will emit a sound and light alarm (red backlight).
6.5. Live/Neutral Wire Check & Breakpoint Detection
- Use the NCV function or the dedicated Live wire detection mode (if available via function button).
- When detecting a live wire, the multimeter will typically show a red backlight and a stronger alarm. For a neutral wire, it may show a green backlight or no alarm.
- For breakpoint detection, run the NCV sensor along the wire. The alarm will stop at the point of the break.
6.6. Flashlight Operation
Press the flashlight/backlight switch button to turn on the integrated LED flashlight for illumination in dark areas.
7. Maintenance
7.1. General Care
- Keep the multimeter clean and dry. Wipe with a soft, damp cloth if necessary. Do not use abrasive cleaners or solvents.
- Store the device in its EVA bag when not in use to protect it from dust and physical damage.
- Avoid exposing the device to extreme temperatures or humidity.
7.2. Battery Charging
Recharge the built-in lithium battery regularly to ensure optimal performance. A low battery indicator will appear on the display when charging is needed.
7.3. Capacitance Measurement Precaution
Important: Before measuring capacitance, always ensure the capacitor is fully discharged to prevent damage to the multimeter or the component being tested.
8. Troubleshooting
- Device does not turn on: Ensure the battery is charged. Connect the multimeter to a Type-C charger and allow it to charge for some time before attempting to power on again.
- Inaccurate readings: Check that the test leads are securely connected to the correct terminals. Ensure the probes are making good contact with the circuit points.
- Automatic shutdown: This is a normal power-saving feature. The device will automatically turn off after approximately 15 minutes of no operation. Simply press the power button to turn it back on.
- No NCV detection: Ensure the NCV sensor at the top of the device is positioned close enough to the voltage source.
9. User Tips
- Always prioritize safety when working with electricity. Ensure power is off before making connections, unless specifically testing for live voltage with appropriate precautions.
- Take advantage of the auto-identification feature for quick and easy measurements, but remember to manually select specific modes for specialized tests like capacitance or diode if needed.
- The large LCD display with red and green backlight is designed for readability. Pay attention to the color changes as they often indicate live voltage or other critical conditions.
- Keep the Type-C charging cable handy to ensure your multimeter is always ready for use, especially given its built-in rechargeable battery.
10. Warranty and Support
