Operating Instructions

1. Battery Test

This function assesses the overall health and charge of your battery.

1. After connecting the tester, select "Battery Capacity" from the main menu.
2. Choose the correct battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, EFB).
3. Input the CCA (Cold Cranking Amps) rating of your battery. If you only know the AH (Ampere-Hour) value, use the built-in CCA/AH conversion feature.
4. The tester will perform the analysis and display results such as State of Health (SOH), State of Charge (SOC), voltage, and internal resistance.

2. Cranking Test

This test evaluates the battery's ability to provide sufficient current to start the engine.

1. From the main menu, select "Cranking Test".
2. Follow the on-screen prompts to start the engine.
3. The tester will analyze the cranking voltage and time, providing a result indicating the battery's cranking performance.

3. Charging System Test

This test checks the vehicle's charging system, including the alternator and voltage regulator.

1. Select "Charge System" from the main menu.
2. Follow the on-screen instructions, which typically involve starting the engine and increasing RPMs.
3. The tester will measure the output voltage and ripple, providing a diagnosis of the charging system's performance.

4. Printing Test Results

The BM550 Ultra features a built-in thermal printer for immediate documentation of test results.

1. After completing a battery, cranking, or charging test, the device will typically prompt you to print the report.
2. Select "YES" to print. The thermal paper will feed out with the detailed test results.
3. Ensure the thermal paper is correctly loaded in the printer compartment.
