  • Check if the battery has sufficient charge (above 8V for 12V systems) for the tester to power on. If the battery is completely dead, the tester may not activate.
  • Verify correct polarity: Red to positive (+), Black to negative (-).
• Inaccurate Readings or "Poor Connection" Message:
  • Clean battery terminals to remove dirt, corrosion, or oxidation.
  • Sørg for at clamps are firmly attached to the battery terminals. Wiggle them slightly to establish better contact.
  • Use the provided copper terminal bolts if the battery terminals are difficult to connect to directly.
• Buttons Seem Unresponsive or Stuck:
  • Press buttons firmly and ensure they return to their original position.
  • If a button remains physically stuck, gently try to free it. Avoid excessive force.
  • Disconnect and reconnect the tester to reset the device.
• Test Results Seem Incorrect:
  • Verify that the correct battery type (Flooded, AGM, GEL, EFB) and CCA rating (if applicable) have been entered into the tester.
  • Ensure all vehicle accessories are off during testing to avoid parasitic draws affecting results.
  • Repeat the test to confirm consistency of results.
