Autel PowerScan PS100 Electrical System Scanner 12V&24V Car Auto Circuit Tester

After a simple hook-up of the tool to the vehicle's battery. I did find a strange operation about it though. Pretty strange but idk if it made to do so. All in all I think it's a great tool for the features and price point, I only hope it lasts just as long as I expect or will it fail too soon.
