  • Try connecting the tester to a different USB port or power adapter.
• Niedokładne odczyty:
  • Check all connections to ensure they are firm and stable. Loose connections can lead to fluctuating or incorrect readings.
  • Test with a different USB cable, as faulty cables can significantly impact charging performance and measurement accuracy.
  • Test with a different power source or load device to isolate if the issue is with the tester or other components.
• Capacity/Energy Data Not Stored:
  • The power-off memory function stores data when the power supply is completely disconnected. Ensure the device is fully powered off or disconnected from the power source for data to be saved.
  • If the power is only momentarily interrupted, the data might not be saved.
• Device Not Charging Through Tester:
  • The tester itself should not prevent charging. If your device is not charging, first bypass the tester to confirm the power source and cable are working.
