2. Setup and Connection

The BM520 battery tester does not require an internal battery for operation; it draws power directly from the vehicle's battery. Ensure the vehicle's engine is off before performing any tests.

2.1 Connecting the Tester

1. Identify the positive (+) and negative (-) terminals on the vehicle's battery.
2. Connect the red clamp of the BM520 to the positive (+) battery terminal.
3. Connect the black clamp of the BM520 to the negative (-) battery terminal.
4. The BM520 features a reversible access design, meaning it can function correctly even if the clamps are connected in reverse. This prevents damage to the tester or battery from incorrect polarity.
5. The device will display a reminder on the screen if the clip connection is loose. Ensure a secure connection for accurate results.

3. Operating Instructions

The BM520 offers multiple testing functions to assess the health and performance of your battery and charging system.

3.1 Battery Test

This function evaluates the overall health of the battery. You will need to input the battery's CCA (Cold Cranking Amps) rating for accurate results.

1. From the main menu, select 'Battery Test'.
2. Input the correct CCA value as specified on your battery.
3. The tester will display the battery's State of Health (SOH), State of Charge (SOC), internal resistance (R), existing battery capacity (CCA), and voltage (V).

3.2 Cranking Test

This test analyzes the actual cranking voltage and time to assess the starting system's performance.

1. Select 'Cranking Test' from the menu.
2. Follow the on-screen prompts to start the engine.
3. The tester will measure and display the cranking voltage and time.

3.3 Charging Test

This function tests various components of the charging system, including the alternator, starter, generator, and rectifier diode, to ensure a reliable charging voltage.

1. Select 'Charging Test' from the menu.
2. Follow the on-screen instructions, which may involve starting the engine and activating various electrical loads.
3. The tester will provide a report on the charging system's performance.

3.4 Load Test

The load test assesses the battery's ability to maintain voltage under load conditions.

1. Select 'Load Test' from the menu.
2. Follow the prompts to apply a load (e.g., turn on headlights).
3. The tester will report on the battery's performance under load.

3.5 Multimeter and Waveform Test

The integrated multimeter function allows testing of voltage and resistance. The waveform test helps verify the stability and reasonableness of the battery's charge/discharge state.

• The BM520 can test voltage and resistance, providing a reference range.
• The waveform test monitors the real-time voltage waveform.
• The device supports recording and playback of up to 5 waveform records.

5. Troubleshooting

If you encounter issues with your BM520, refer to the following common problems and solutions.

• Device not powering on: Ensure the clamps are securely connected to the battery terminals. The device draws power from the battery. Check battery voltage; if it's too low (below 4.9V), the device may not power on.
• Inaccurate test results: Verify that the engine is off during the test. Ensure the battery type and CCA values are correctly entered. Check for loose clamp connections. Clean battery terminals and tester clamps if corroded.
• Screen display issues: The BM520 features a 2.8-inch HD color screen for clear results. If the display is unclear or distorted, try restarting the device by disconnecting and reconnecting the clamps.
• Difficulty with software update: Ensure the USB cable is properly connected to both the device and the computer. Verify that the update file is correctly placed on the removable disk drive. Try using a different USB port or computer if issues persist.
