Product selling points and features:

1. It has a reverse connection alarm and overvoltage protection functions. The red clip is connected to the positive pole “+”, and the black clip is connected to the negative pole “-“. If it is reversed, the LED display screen will not display, and the REVERSE indicator light will light up and issue an alarm prompt

2. Equipped with an LED reverse display screen with a clear backlight, the reverse display screen can be displayed during testing, and the measured values can be clearly seen at night or in dark places to assist in measurement work, making it easy to read

3. After the correct connection, the LED display screen will display the real-time voltage of the measured voltage and the LED light will light up to indicate the battery status

4. Test the charging system status of the generator: During the test, please ensure that the tester is correctly connected to the battery terminal, and then start the generator. At this time, the output voltage will be displayed on the LED display screen, and the right LED indicator light will light up to indicate the generator status

5. No need to install batteries, easy to complete multiple tests, using live measurement

Cautions for use：

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: The LED light is on, the battery voltage is too low, and the 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

REVERSE – 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
