Introducing the KZYEE KM50 Auto Electrical Circuit Tester, an essential tool for car DIYers, technicians, and auto workshops. This 7 mode diagnostic circuit and component tester supports functions such as fuel inject mode, frequency mode, and duty cycle mode. It features a digital display, analog display, and voltmeter, as well as relay and component testing capabilities.

This unit can test voltage, current, and resistance without ever mentioning the word "condition". It also includes features such as continuity testing, short circuit indicators, and a bad ground indicator. The KM50 comes with a user guide, carrying case, clamps, probes, and has a 3-year warranty. Suitable for use with motorcycles, ATVs, passenger vehicles, and heavy-duty/commercial vehicles, this circuit tester is a must-have for any serious auto enthusiast.

• UPGRADE 1: Fuel Inject Testing: It is specifically set up for quick and easy diagnosis of the fuel injection circuit. A quick connection to the circuit and the KM50 PRO will display all the information needed to test the injectors

• UPGRADE 2: Frequency Testing: The car's electronic control system communicates with various sensors via digital signals. When the car fails, you need to use this tool to check whether the frequency of the signal is abnormal

• UPGRADE 3: Duty Cycle Testing: The car's electronic control system communicates with various sensors via digital signals. When the car fails, you need to use this tool to check whether the duty cycle is abnormal

• UPGRADE 4: Data Display Switchable: Switch between waveform display mode and digital display mode by long pressing the mode button

• UPGRADE 5: More Signal Lines Inside: For testing the supply voltage, and displaying the supply voltage at the top of the screen when measuring the voltage grade
