2. Safety Information

Always observe basic safety precautions when using this multimeter to avoid personal injury or damage to the device. Read all instructions carefully before use.

• Do not exceed the maximum input values specified for each measurement range.
• Exercise extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. Such voltages pose a shock hazard.
• Before measuring current, ensure the multimeter is connected in series with the load and the correct function is selected.
• Before measuring resistance, continuity, diode, or capacitance, ensure the circuit is de-energized and all capacitors are discharged.
• Do not use the multimeter if it appears damaged or if the test leads are damaged.
• Always use the correct terminals, function, and range for your measurement.
• Keep hands and fingers behind the probe barriers during measurements.
• Do not operate the multimeter in explosive gas, vapor, or dust environments.
• Refer to the specifications section for detailed measurement limits.

5. Setup

5.1 Charging the Battery

The BSIDE A1X Multimeter comes with a built-in rechargeable Lithium-ion battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB charging cable.

1. Connect the small end of the USB charging cable to the charging port on the multimeter.
2. Connect the other end of the USB cable to a standard USB power adapter (e.g., phone charger, computer USB port).
3. The charging indicator light will show the charging status. Once fully charged, the light may change color or turn off.

5.2 Connecting Test Leads

For most measurements, you will need to connect the test leads to the multimeter.

1. Insert the black test lead into the "COM" (Common) input jack.
2. Insert the red test lead into the "INPUT" jack.
3. Ensure the connections are firm and secure before taking any measurements.

6. Operating Instructions

6.1 Power On/Off

Press and hold the power button (ⓘ) to turn the multimeter on or off.

6.2 Automatic Mode (AUTO)

Upon powering on, the multimeter defaults to Automatic Mode. In this mode, the device intelligently identifies and measures AC/DC voltage, resistance, and continuity without manual range selection.

Figure 6.1: The multimeter's display indicating the automatic mode selection, where it can detect and measure AC/DC voltage, resistance, continuity, NCV, and Live functions.

6.3 Manual Mode Selection

Press the "AUTO SEL" button to cycle through manual measurement functions: Voltage (AC/DC), Resistance (Ω), Diode, Capacitance, and Continuity. The selected function will be indicated on the display.

6.4 Voltage Measurement (AC/DC)

To measure voltage:

1. Ensure test leads are connected correctly (Black to COM, Red to INPUT).
2. If not in Auto mode, press "AUTO SEL" until the voltage icon (V) is displayed.
3. Connect the test probes in parallel to the circuit or component you wish to measure.
4. Read the voltage value on the display. The display will show "DC" or "AC" to indicate the type of voltage.

6.5 Resistance Measurement (Ω)

To measure resistance:

1. Ensure the circuit is de-energized.
2. If not in Auto mode, press "AUTO SEL" until the resistance icon (Ω) is displayed.
3. Connect the test probes across the component or circuit where you want to measure resistance.
4. Read the resistance value on the display.

6.6 Continuity Test

To test for continuity:

1. Ensure the circuit is de-energized.
2. If not in Auto mode, press "AUTO SEL" until the continuity icon (⦁)) is displayed.
3. Connect the test probes across the circuit or component.
4. If resistance is less than 50Ω, the buzzer will sound, indicating continuity.

6.7 Diode Test

To test a diode:

1. Ensure the diode is disconnected from any power source.
2. If not in Auto mode, press "AUTO SEL" until the diode icon (➟|△) is displayed.
3. Connect the red probe to the anode and the black probe to the cathode of the diode.
4. Read the forward voltage drop on the display. Reverse the probes; an open circuit (OL) reading indicates a good diode.

6.8 Capacitance Measurement

To measure capacitance:

1. Ensure the capacitor is fully discharged before testing.
2. If not in Auto mode, press "AUTO SEL" until the capacitance icon (—||—) is displayed.
3. Connect the test probes across the capacitor terminals.
4. Read the capacitance value on the display.

6.9 Non-Contact Voltage (NCV) Detection

The NCV function allows detection of AC voltage without direct contact with wires.

1. Press the "V-Alert" button to activate NCV mode.
2. Move the top tip of the multimeter close to the wire or outlet.
3. The display will show "NCV" and the backlight will turn red, accompanied by a buzzer sound, indicating the presence of AC voltage. The intensity of the beeps and light indicates signal strength.
4. Press the "V-Alert" button again to adjust sensitivity (High/Low).

6.10 Live Wire Check

This function helps identify live (phase) and neutral wires.

1. Press "AUTO SEL" until the "LIVE" icon is displayed.
2. Insert the red test probe into the socket or touch the wire.
3. If it's a live wire, the display will turn red, show "LIVE", and the buzzer will sound. For a neutral wire, the display will remain green and show "NEU".

6.11 Display Backlight

The multimeter features a red and green backlight. The green backlight indicates normal operation, while the red backlight often indicates a high voltage detection (above 90V) or a live wire detection.

7. Maintenance

7.1 Cleaning

Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and disconnected from any power source before cleaning.
