Continuity Testing

KM50 Electrical Circuit Diagnostic Tester KM-50 Automotive Power Analyser The KZYEE KM50 Power Scan Kit is the most revolutionary circuit tester to date, working with 12-24 volt sources and providing DC voltage, AC voltage, Frequency, Duty Cycle, Injector Circuit, Resistor and Diode detection functions. Specifically in AC voltage, Frequency, Duty Cycle and Inject mode, the user can switch between waveform display mode and digital display mode by long pressing the mode button. The Power Scan is indeed the ultimate in performance and affordability, allowing the user to check circuits in a single step. An absolute must for any technician looking for a fast and accurate solution for diagnosing electrical systems. TIPS: 1. KM50 is ONLY for 12-24V vehicle battery electrical systems, and should NOT be used to test 110/220V household appliances or it will be damaged. 2. The LED and LCD draw no more than 100 milliamps of current. So if you use this device as a test light or multimeter, it is safe for computers and airbags. 3. When turning on components, you can extend the life of rocker switch in the tool if you first press the switch, and then apply the tip to the component. The arc will then occur at the tip and not at the metal contacts of the rocker switch. Function: ✔️ Diagnose 12 ~24V automotive electrical systems swiftly and accurately. ✔️ Show battery voltage reading and help user determine circuit polarity immediately after connecting the KM50 clips to the vehicle battery. ✔️ Test DC Voltage, AC Voltage, Frequency, Duty Cycle, Fuel Injection Circuit, Resistance, and Diode. Especially, in AC Voltage, Frequency, Duty Cycle and Fuel Inject Modes, user can long press the mode button for 3 seconds to switch between Waveform Display Mode and Digital Display Mode. ✔️ Activate electrical components and test their functions without jumper leads – by depressing the rocker switch to conduct a positive or negative battery current to the tip so as to power up electrical components. ✔️ Test bad ground contacts instantly without performing voltage drop tests. ✔️ Help user to follow and locate short circuits without using external fuses. ✔️ Test continuity with the assistance of its auxiliary ground lead. ✔️ The tool is short-circuit protected. If it becomes overloaded, Its internal circuit breaker will trip to protect the instrument from overload. ✔️ When the circuit breaker is tripped, the tool will NOT be able to conduct battery current to the tip even when the rocker switch is pressed; however, all other functions of the tool are still active, which means you can still probe a circuit and observe the voltage reading. 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. More Advance Features to Do Circuit Test 1. 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. 2. 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. 3. 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.
