Product Details
✓Find Electrical Problems Faster — Use the KM50 automotive electrical tester and power circuit probe to check voltage, polarity, continuity, short circuits, open circuits and bad grounds on 12V/24V vehicle systems
✓See Signals as They Change — View digital readings or a live waveform to check AC voltage, frequency, duty cycle and changing sensor signals while troubleshooting
✓Check Fuel Injector Circuits — Use the dedicated fuel injector circuit tester mode to check injection time, supply voltage, induced voltage, ground voltage and control waveform
✓Trace Shorts and Bad Grounds — Use the KM50 as an automotive short circuit finder to follow suspected wiring, check continuity and narrow down shorts, open circuits and poor ground connections
✓Power and Test Components — Use component activation to send positive power or ground from the probe tip and check supported components without separate jumper leads
✓Test Before Replacing Parts — Seven test modes cover DC Voltage, AC Voltage, Frequency, Duty Cycle, Fuel Injection Circuit, Resistance and Diode to help confirm the circuit before replacing parts
✓Easy to Read. Protected to Test. — A color TFT display, red/green polarity LEDs, work light and buzzer give clear feedback, while the built-in circuit breaker helps protect the tool during testing
