8. Maintenance

• Keep the device clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
• Store the tester in a dry, cool place away from direct sunlight and extreme temperatures.
• Regularly inspect the diagnostic cable and clamps for any signs of damage. Replace if necessary.
• Do not attempt to disassemble or repair the device yourself. Refer to qualified service personnel.

9. Troubleshooting

9.1 Device Does Not Power On

• Check Connections: Ensure the red and black clamps are securely connected to the correct battery terminals.
• Battery Voltage: Verify that the battery has sufficient voltage (at least 6V for 6V batteries, 8V for 12V batteries) to power the tester.
• Cable Integrity: Inspect the diagnostic cable for any cuts or damage.

9.2 Inaccurate Test Results

• Clean Terminals: Ensure battery terminals are clean and free of corrosion for optimal contact.
• Correct Battery Type/Rating: Double-check that the correct battery type (e.g., GEL, AGM) and CCA rating are selected in the tester's settings.
• Temperature: Extreme battery temperatures can affect readings. Allow the battery to normalize to ambient temperature if possible.

9.3 Tester Freezes or Malfunctions

• Restart Device: Disconnect the tester from the battery, wait a few seconds, and then reconnect it.
• Software Update: Check the manufacturer's website for any available software updates for the device.

10. User Tips

• For the most accurate cranking test results, ensure the engine is completely off and has not been recently run.
• Regularly use the waveform analysis feature to track subtle voltage changes over time. This can help identify early signs of battery degradation before it becomes a major issue.
• Always confirm the battery's specified CCA rating and type before initiating a test to ensure the most precise measurements.
• If testing a battery out of the vehicle, ensure it is fully disconnected from any charging or load sources.
