The KZYEE KM50 Circuit Tester Kit is an improved version of the KM10 that performs all types of tests, such as DC voltage, AC voltage, resistance and diode. It also has the latest improved functions for testing signal frequency, duty cycle and fuel injection. This allows the mechanic to trace and identify the problem circuit and rule out good circuits, speeding up the diagnostic process and revealing the true cause of the electrical problem much easier.
With the ability to power components such as radiator fans, starters, relays, power windows, windshield wipers, and so on. It can activate electrical components and test their functions without jumper cables - by pressing the toggle switch to send a positive or negative battery current to the tip and turn on the electrical components.
If the vehicle has difficulty starting, acceleration, fuel consumption, etc., it’s necessary to check the fuel injection system. KM50 Fuel Inject Test is specially designed for quick and easy diagnosis of fuel injection circuit. It can be quickly connected to the circuit and displays all the information needed. The addition of Frequency and Duty Cycle modes, which many other models do not have, makes the KM50 a versatile digital tool simplifies the diagnosis and repair of electrical problems.
It works with a 12-24V DC power source. Switching from one test mode to another is effortless. It also speeds up circuit troubleshooting and diagnosis by switching the waveform display from digital to AC voltage, frequency, duty cycle and fuel injection tests by pressing the mode button for 3 seconds.
The built-in flashlight is bright enough to illuminate your work area, and the flashlight and buzzer itself can be turned off. Red/Green Polarity Indicator - Identifies positive, negative or open circuits. The RED indicator lights when the probe tip touches a positive circuit. The GREEN indicator lights when the probe tip touches a negative or negative voltage circuit. When measuring resistance, the green indicator lights when the resistance is less than 30Ω
