Check the listing for details. KM50 12V 24V PowerScan Circuit Probe Kit Fuel Injector Digital Electrical Tester. Condition: New. Listed at 83.99 USD. About this itemThe 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 30ΩKM50 Electrical System Circuit Tester Functions:1. Perform these functions: power injection, measuring, ground testing, polarity checking, continuity testing and component activation.2. Support 7 diagnostic model:Fuel Inject Mode, Frequency Mode, Duty Cycle Mode, DC Voltage Mode, AC Voltage Mode, Resistance Testing Mode, Diode Testing Mode3. Press the power switch lightly and get the instant heat ground lead to energize the electrical components, such as the cooling fan, relay etc.4. Activate the components by using the hot wire and ground lead simultaneously.5. Determine the positive, negative and open circuit quickly.6. Test the bad ground contacts quickly, follow and locate short circuits without wasting the fuse.7. Test the continuity of the power switch, relay and diode quickly.8. Protect the tool from overload through the inner circuit breaker.9.Operate the tool without looking at the menu once users are familiar with the tone. Test along the vehicle by the long cable.KM50 has more highlights than other circuit testers. Resistance Test: While the tool in this mode, contact the probe tip to a circuit, then the LCD display will read the resistance between the tip and auxiliary ground lead. Diode Test: In this mode, the probe tip contact the positive terminal of the diode, connect the auxiliary ground lead to the negative terminal of the diode, the screen will display the forward voltage drop, indicates the forward bias. If exchange the probe tip and auxiliary ground lead, the screen will not display the voltage, indicates the reverse bias. Signal Circuit Testing: Once you extract a DTC from the vehicle and realize that troubleshooting begins with some kind of sensor circuit, there is a quick test you can perform to verify the code. Testing your sensor is easy while using the tool. Testing Trailer Lights and Connections: While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer ground , probe the contacts at the jack and then apply voltage to the probe tip. This lets you check the function and orientation of the connector and trailer lights. Red/Green Polarity LED: The Red/Green Polarity LED lights up when the probe tip voltage matches the battery voltage within ±0.4 volts. It is added information that could be valuable to the technician. Auto Circuit Breaker: The tool is short-circuit protected. Its internal circuit breaker will trip if it becomes overload. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload. NEW FEATURES More Advance Features to Do Circuit Test: Fuel Inject Mode: There are a variety of currently used techniques and tools that can test a fuel injector or injector circuitry; however it usually involves using multiple tools and tests to check every aspect of the injector circuit. Complete testing could take quite a bit of time. Fuel Inject Mode is specifically set up for quick and easy diagnosis of the fuel injection circuit. A quick connection to the circuit and the KM50 will display all the information needed to test the injectors. To reset the maximum and minimum values, press the mode button twice. If no valid injector pulse is detected in this mode, a bar icon will be displayed instead. Frequency and Duty Cycle Mode: The car's electronic control system communicates with various sensors via digital signals. When the car fails, you need to use the instrument to check whether the frequency of the signal or the duty cycle is abnormal. Press the Mode button to enter the menu, and press the Down button momentarily to place the cursor in the frequency mode, and press the Mode button momentarily to enter the frequency waveform display mode. Press the Mode button to enter the menu, and press the Down button momentarily to place the cursor in the Duty Cycle mode, and press the Mode button to switch to the waveform display. Buzzer and LED light are Switchable: When you measure the voltage DC, if the voltage is 0V, the green indicator light will be on and the buzzer will sound twice; if the voltage is above 5V, the red indicator light will be on and the buzzer will sound once. When the resistance value is less than 30Ω, the buzzer of the device sounds and the green indicator LED lights up.
