7. Troubleshooting

If you encounter issues with your MR CARTOOL B200, consider the following common solutions:

• Device Not Powering On: Ensure the red and black clamps are securely connected to the correct battery terminals. The device draws power directly from the battery. If the battery is completely dead (below 6V), the tester may not power on.
• Inaccurate Readings: Verify that the correct battery type and rated CCA/AH values are entered into the tester. Ensure battery terminals are clean and connections are solid.
• Error Messages: Refer to the specific error code or message displayed on the screen and consult the detailed user manual for corresponding solutions.
• Loose Cable Detection: If the device indicates loose cables, re-secure the clamps to the battery terminals.

8. Maintenance

Proper maintenance ensures the longevity and accuracy of your MR CARTOOL B200:

• Cleaning: Wipe the device with a soft, dry cloth after each use. Avoid using abrasive cleaners or solvents.
• Storage: Store the tester in a dry, cool place away from direct sunlight and extreme temperatures. Keep the clamps clean and free of corrosion.
