4. Operation
The KVB01 offers four main test modes. Use the navigation buttons (Up/Down arrows) to select a mode and the "M ENTER" button to confirm.
4.1. Battery Test
This test assesses the overall health and lifespan of the battery.
- From the main menu, select "Battery Test" and press "M ENTER".
- Input the battery's CCA (Cold Cranking Amps) rating. This can usually be found on the battery label. Use the arrow buttons to adjust the value and "M ENTER" to confirm.
- The tester will display results including State of Charge (SOC), State of Health (SOH), Voltage, CCA value, and Internal Resistance (RES).

4.2. Cranking Test
This test measures the battery's discharge performance during engine startup.
- From the main menu, select "Cranking Test" and press "M ENTER".
- Follow the on-screen prompts to start the engine.
- The tester will analyze the dynamic voltage during cranking and display the cranking voltage and standard voltage.

4.3. Charging Test
This test evaluates the performance of the vehicle's charging system (alternator).
- From the main menu, select "Charging Test" and press "M ENTER".
- Follow the on-screen prompts to start the engine and run it at idle.
- The tester will analyze the dynamic voltage, maximum voltage, and minimum voltage of the charging system.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester does not power on. | Incorrect connection to battery terminals. Battery voltage too low. | Ensure red clip is on positive (+) and black clip on negative (-). Check battery voltage; if below 9V, the tester may not power on. |
| Inaccurate test results. | Loose connections. Incorrect CCA input. Battery terminals are dirty. | Ensure clips are securely attached. Verify the CCA value entered matches the battery's rating. Clean battery terminals if corroded. |
| Screen displays "Error" or "Warning". | Battery fault detected. System fault during test. | Refer to the specific error code on the screen for detailed information. Re-run the test. If the error persists, the battery or charging system may require professional inspection. |
