LED light related instructions:

FULL - Fully charged: LED light on, battery in normal state

MEDIUM medium power: LED light is on, battery voltage is slightly low and needs to be charged

LOW - Low battery: LED light is on, battery level is low and needs to be charged, beep alarm

EMPTY - No battery: LED light is on, battery is completely dead and needs to be charged

High voltage: LED light is on, and the output voltage of the AC generator is high

Good voltage: LED light is on, and the output of the AC generator is normal

DEAD fault: LED light is on, battery voltage is too low, buzzer alarm indicates that there should be a problem with the battery. At this time, the battery should be inspected by a professional engineer to see if it needs to be replaced

RECERSE - Reverse connection of positive and negative poles: The LED light is on, the battery tester is connected in the opposite direction to the battery terminal, and the buzzer alarms
