3. Setup

3.1 Initial Charging

Before first use, it is recommended to fully charge the built-in lithium-ion battery. Use the provided USB cable to connect the multimeter to a standard USB power source (e.g., computer USB port, USB wall adapter). The charging indicator will show the charging status.

3.2 Connecting Test Leads

For most measurements, connect the black test lead to the COM (Common) input terminal and the red test lead to the INPUT terminal. Ensure the connections are secure before taking any measurements.

4. Operating Instructions

The BSIDE A1X features intelligent auto-ranging, simplifying most measurements. Press the power button to turn on the device. It will typically start in auto mode.

4.1 Auto Mode Operation

In auto mode, the multimeter automatically detects the type of measurement (voltage, resistance, continuity) and selects the appropriate range. Simply connect the test leads to the circuit or component you wish to measure.

Figure 4: Auto Mode Selection and supported measurement types.

4.2 Specific Measurement Functions

While in auto mode, you can press the function mode switching button to cycle through specific measurement types if needed, or use dedicated buttons for Capacitance and Diode testing.

Figure 5: Various measurement applications of the multimeter.

• Voltage Measurement (AC/DC): Connect the test leads in parallel to the circuit. The multimeter will automatically detect AC or DC voltage.
• Resistance Measurement: Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
• Continuity Test: Used to check if a circuit is open or closed. A buzzer will sound if continuity is detected (resistance below 50Ω).
• Capacitance Measurement: Important: Discharge capacitors before measuring to avoid damage to the meter. Connect the test leads across the capacitor.
• Diode Test: Connect the test leads across the diode. The display will show the forward voltage drop.

4.3 Non-Contact Voltage (NCV) Detection

To use the NCV function, hold the top of the multimeter near the conductor. The device will indicate the presence of AC voltage through visual and audible alerts. This is useful for quickly checking for live wires without direct contact.

4.4 Live/Neutral Wire Check

The multimeter can help distinguish between live and neutral wires. By comparing the strength of the detected voltage signal, the wire with the stronger signal is identified as the live wire.
