3. Setup

3.1. Charging the Battery

The BSIDE A5X is equipped with a built-in 700mAh rechargeable lithium-ion battery. Before first use, or when the low battery indicator appears, charge the device using the provided Type-C charging cable.

1. Connect the Type-C end of the charging cable to the multimeter's charging port.
2. Connect the USB-A end of the cable to a standard USB power adapter (not included) or a computer USB port.
3. The charging indicator on the multimeter will show the charging status. Once fully charged, the indicator will change or turn off.

3.2. Initial Power On

Press and hold the power button (⏻) to turn on the multimeter. The device will typically start in Smart Mode, automatically detecting the measurement type.

4. Operating Instructions

The BSIDE A5X features an intelligent auto-identification system that simplifies measurements. In Smart Mode, it automatically detects and measures AC/DC voltage, AC/DC current, resistance, continuity, and frequency. For other functions, use the dedicated buttons.

4.1. Smart Mode Operation

When powered on, the multimeter defaults to Smart Mode. Simply connect the test leads to the circuit or component, and the meter will automatically identify and display the measurement (Voltage, Current, Resistance, Continuity, or Frequency).

4.2. Measuring AC/DC Voltage

In Smart Mode, the meter automatically measures AC or DC voltage. Connect the red test lead to the 'VΩHz' input jack and the black test lead to the 'COM' input jack. Place the probes across the circuit points to measure voltage.

Figure 4.1: The BSIDE A5X Multimeter automatically measures AC voltage, displaying both the voltage value and frequency.

4.3. Measuring AC/DC Current

For current measurements, the A5X features smart identification. Plug the test leads into the appropriate current input port (600mA for current measurements) and the 'COM' port. The tester will automatically switch to AC/DC ampere test mode.

Figure 4.2: The BSIDE A5X Multimeter features Amp Smart Identification; simply plug into the amp port, and the tester automatically switches to AC/DC ampere test mode.

4.4. Measuring Resistance

In Smart Mode, connect the test leads across the resistor. The meter will automatically detect and display the resistance value.

4.5. Measuring Capacitance

To measure capacitance, press the 'FUNC' button until the capacitance symbol (μF) appears on the display. Important: Always discharge the capacitor before measuring to prevent damage to the meter or injury. Connect the test leads across the capacitor terminals.

4.6. Measuring Frequency and Duty Cycle

In Smart Mode, frequency is automatically displayed when measuring AC voltage. For dedicated frequency or duty cycle measurements, press the 'FUNC' button to cycle through modes until the Hz or % symbol appears. Connect the test leads to the signal source.

4.7. Measuring Temperature

Connect the provided thermocouple to the multimeter's input jacks (ensure correct polarity). Press the 'FUNC' button until the temperature symbol (°C or °F) appears. Place the thermocouple probe at the point where temperature needs to be measured. The A5X can display both thermometer temperature and ambient environment temperature.

Figure 4.4: Dual-Way Temperature Test. The multimeter can measure both thermometer temperature (0°C~1000°C) and environment temperature (0°C~50°C).

4.8. Diode Test

Press the 'FUNC' button to select the diode test mode. Connect the red test lead to the anode and the black test lead to the cathode of the diode. The display will show the forward voltage drop. For a good silicon diode, this is typically around 0.5V to 0.8V. An open circuit (OL) indicates a faulty diode or incorrect polarity.

4.9. Continuity Test

In Smart Mode, continuity is automatically detected. Alternatively, press the 'FUNC' button to select continuity mode. Connect the test leads across the circuit or component. If the resistance is below approximately 30Ω, the meter will emit an audible beep, indicating continuity.

4.10. Non-Contact Voltage (NCV) Detection

The NCV function allows for detection of AC voltage without direct contact. Press the 'V-Alert' button to activate NCV mode. Move the top tip of the multimeter near the conductor. The meter will indicate the presence of AC voltage through visual and audible alerts. The A5X offers high and low sensitivity settings for NCV detection.

4.11. VFC (Variable Frequency Control) Test

The VFC function is designed to measure the output voltage of variable frequency drives (VFDs) or inverters. Press the 'FUNC' button to select VFC mode. Connect the test leads to the output of the VFD. This mode provides accurate readings for non-sinusoidal waveforms.

Figure 4.5: The VFD function allows the BSIDE A5X Multimeter to accurately measure the output voltage of inverters.

4.12. Automotive Circuit Test

The BSIDE A5X can be used for various automotive electrical tests, such as checking battery voltage, alternator output, and continuity in wiring. Ensure the vehicle's electrical system is off before connecting test leads for continuity or resistance checks. For voltage checks, connect leads to the appropriate points (e.g., battery terminals).

5. Maintenance

5.1. Cleaning

Wipe the meter's casing with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is off and disconnected from any circuits before cleaning.

5.2. Battery Care

To prolong battery life, avoid fully discharging the battery frequently. Recharge the battery when the low battery indicator appears. If storing the meter for an extended period, charge it periodically to maintain battery health.

5.3. Fuse Replacement

The BSIDE A5X is equipped with an easy-to-replace fuse for overload protection. If the current measurement function stops working, the fuse may need replacement. Refer to the specifications for the correct fuse type and rating. Disconnect all test leads and power off the meter before attempting fuse replacement.

6. Troubleshooting

• No Display/Meter Not Turning On: Check battery charge level. Ensure the power button is pressed and held sufficiently.
• Incorrect Readings: Verify test lead connections. Ensure the correct measurement function is selected (if not in Smart Mode). Check for damaged test leads.
• No Current Measurement: Check the fuse. Ensure test leads are connected to the correct current input jack.
• Continuity Beeper Not Working: Ensure continuity mode is selected. Check if the resistance is above the threshold (approx. 30Ω).
• NCV Not Detecting: Ensure NCV mode is active. Check for proper proximity to the AC voltage source.
