 Digital circuit tester.
 
 Breaker Finder Mode enables you to easily locate the circuit breaker point, open connections, broken wires, current leaks with tone change, and even trace wire/cable without damaging the insulation.
This circuit breaker finder tool works on all kinds of vehicle circuit issues such as those found in cars, SUVs, minivans, trucks, tractors, boats & RVs.
The oscilloscope and multimeter Mode has features such as: Voltage (VDC), Resistance(OHM), Diode (DIO), Current (AMP), Frequency (HZ), and Polarity.
The Oscilloscope module is an electronic test instrument that displays electrical signals graphically, This function can show the fluctuation of data more intuitively.
 Injector Test feature uses a probe tip to output different pulse signals to the injector and check the injector spraying status. This feature can help diagnose injector conditions.
0-5V Power Supply provides a stable, adjustable, low-voltage power supply to simulate input voltage, debug sensors, test circuit behavior, and calibrate systems. It is especially suitable for debugging and diagnosing low-power electronic devices and sensor systems.
 Component Activation & Signal Circuit Tests provides power to various car parts like bulbs, radiator fans, starter motors, relays, window regulators, and windshield wipers, enabling effective testing and troubleshooting..
Locate auto short circuits if you keep getting blown fuses and also test various sensors, and signal circuits to pinpoint the root cause of electrical issues when you have extracted DTCs from vehicle ECUs.
