Car injector tester - digital display multimeter for electric system1、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, car and truck can realize the whole circuit detection with simple operation. 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 resistance and voltage, and intelligently judge the positive and negative electrodes of the circuit battery. 3、Oscilloscope Function: The high grade automotive power circuit analyzer features the function of oscilloscope, the maximum analog bandwidth is 50KHz, and the maximum sampling rate is 800KSa/s, greatly bring you 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. 5、0‑5V Power Supply Mode: The voltage output by the sensor can be simulated to the ECU to verify the wiring of the ECU. It can easily generate a variable DC voltage (0‑5V) for emergency scenarios where there is no adjustable power supply, but a small voltage connection is required. 6、Use of Adjustable Power Supply: 1. Set the electric pen to output a suitable voltage (up to 5V 200mA); 2. It can be connected to the power supply terminal of low‑voltage power supply equipment (ECU, sensor); 3. Observe.
