Alternator Charging System Analyzer : Except for providing a quick reading to determine if a vehicle battery needs a jump or replacing, It can also test the alternator output status to avoid damaging the battery because of overcharge or incomplete charge.
Easy Operation ]: We creatively designed three gears to test the alternator, 12V battery, and 24V battery respectively. When keeping the gear in the middle, the LCD screen displays the real-time voltage, the LEDs indicate the alternator status, When shifting to 12V or 24V gear, the LCD screen displays the real-time voltage and the LEDs indicate battery status.
Reverse-hookup & Over-voltage protection: While connected reversed, the LCD screen will display the error code 'ERR' and the built-in buzzer will sound. The Digital Voltage test range is 4-30V DC, when the voltage is out of range, the screen will display 'LO'(<4V) or ‘HI’ (>30V).
