1.Easy to Use: Multimeter and oscilloscope are integrated, large 3.2 horizontal screen display, intuitive menu interface, easy to learn and use, long extension cable, can realize the whole circuit detection for cars and trucks simply. 2.Intelligent Digital Display: Meet all the functions of the multimeter (VDC/OHM/DIO/AMP/HZ), can continuously test the circuit or components of the circuit system, automatically measure the current and voltage, and intelligently judge the positive and negative electrodes of the circuit battery. 3.Oscilloscope Function: The grade automotive power circuit analyzer has the function of oscilloscope, the maximum analog bandwidth is 50KHz, and the maximum sampling rate is 800KSa/s, which greatly brings more convenience. 4.Component Activation: Used to generate activation signals to the detected components, such as activating lights. There are two activation methods, positive activation and negative activation. The maximum current through activation can reach 20A. There are three activation methods: MOMENT, LACH, and PULSE.
