ANENG BT-171 12V Multifunctional Battery Testers Auto Repair Industry Detection with LED Reverse Display Screen Electrician Tool

The functions of BT-171 and BT-172 are the same. The difference between them is that the BT-171 product has instructions for operation on the front, while the BT-172 product has instructions for operation in English on the front. After changing the model, the functional attribute parameters of both products are the same. Please understand

Features:

1. Small and portable
2. High sensitivity, fast response, simple and convenient operation
3. Widely used in the auto repair industry: especially applicable to the maintenance and repair of automobiles, electric vehicle repair technicians, families and enterprises
4. It has the function of reverse connection alarm and overvoltage protection. The red clip is connected to the positive pole "+" and the black clip is connected to the negative pole "-". If the connection is reversed, the LED display will not display, and the REVERSE indicator will light up and give an alarm prompt
5. With an LED reverse display screen, the backlight is also clear, and the test shows the reverse display screen, and the measured value can be clearly seen at night or in the dark to assist the measurement work, and easy reading
6. After the connection is correct, the LED display will display the real-time voltage of the measured voltage, and the LED will light up to indicate the battery status
7. Test the state of the generator charging system: during the test, please keep the tester and the battery terminal correctly connected, and then start the generator. At this time, the output voltage will be displayed on the LED display, and the right LED indicator will light up to indicate the state of the generator
8. It is easy to complete multiple tests without installing batteries, and use live measurement
