6.2. Battery Test
This test measures the battery's Cold Cranking Amps (CCA), State of Health (SOH), State of Charge (SOC), voltage, and internal resistance.
- From the main menu, select "Battery Test".
- Select the battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, EFB).
- Enter the rated CCA value of your battery (usually found on the battery label).
- The tester will display the results, including SOH, SOC, actual CCA, voltage, and internal resistance, along with a recommendation (e.g., "Good Battery", "Replace Battery").
6.3. Cranking Test
This test evaluates the vehicle's starting system by measuring the minimum cranking voltage.
- From the main menu, select "Cranking Test".
- Follow the on-screen prompts to start the vehicle's engine.
- The tester will record the minimum voltage during cranking and display the result, indicating if the cranking system is performing adequately.
6.4. Charging Test
This test checks the output of the vehicle's charging system (alternator, regulator, diodes).
- From the main menu, select "Charging Test".
- Follow the on-screen prompts to start the engine and rev it to the specified RPM (if prompted).
- The tester will display the charging voltage and ripple, indicating the health of the charging system.
6.5. Historical Data Review
The BT360 stores previous test results, allowing you to review them for diagnostic purposes.
- From the main menu, select "Settings".
- Select "Review" to access the historical test data.
