5. Operating Instructions (Battery Tester)
5.1 Battery Test
This function tests the overall health of the battery.
- From the main menu, select "Battery Test".
- Select the battery type (e.g., Regular Flooded, AGM Flat Plate, AGM Spiral, Gel).
- Select the battery standard (e.g., CCA, JIS, EN, DIN, SAE).
- Input the rated CCA or AH value of the battery, typically found on the battery label.
- Confirm the battery temperature (above or below 0°C).
- The tester will display the results, including CCA, voltage, internal resistance, SoH, and SoC.

5.2 Cranking Test
This test evaluates the vehicle's starting system, including the starter motor.
- From the main menu, select "Cranking Test".
- Follow the on-screen prompts to start the vehicle.
- The tester will analyze the cranking voltage and duration.
- Results will indicate if the cranking system is normal or if issues are detected.
5.3 Charging Test
This test assesses the vehicle's charging system, including the alternator.
- From the main menu, select "Charging Test".
- Follow the on-screen prompts to run the engine at specified RPMs.
- The tester will measure unloaded voltage, loaded voltage, and ripple voltage.
- Results will indicate if the charging system is normal or if issues are detected.

8. Troubleshooting
8.1 Battery Tester Issues
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester does not power on. | Poor connection to battery terminals; battery completely discharged. | Ensure clamps are securely connected to clean battery terminals. Check battery voltage with a multimeter; if extremely low, charge battery first. |
| Inaccurate readings. | Incorrect battery type/standard/CCA input; loose connections; dirty terminals. | Verify battery information entered into the tester. Clean battery terminals and re-establish secure connections. |
| "Bad Cell, Replace" message. | Battery has one or more faulty cells. | The battery is likely beyond repair and requires replacement. |
