KM50 Power Circuit Probe & Automotive Circuit Tester with Live Waveform (Orange)

Key Features

• 【Go Beyond Basic Circuit Testing】Updated from the KZYEE KM10, the KM50 combines a 12V/24V automotive power circuit probe and automotive circuit tester with 7 dedicated test modes for deeper circuit and signal diagnosis. Along with voltage, continuity, polarity, short-circuit tracking and open-circuit identification, it adds dedicated frequency, duty cycle and fuel injection analysis for serious DIYers and independent technicians who need more than basic electrical checks
• 【Dedicated Signal Analysis】The KM50 switches between digital readings and live waveform display in AC voltage, frequency, duty cycle and fuel injection modes, showing how electrical signals change over time. Dedicated signal modes help identify changing readings, unstable signals and abnormal circuit behavior that basic voltage checks alone may not fully explain
• 【Fuel Injection Circuit Diagnosis】The dedicated Fuel Inject mode displays injection time, injector supply voltage, reverse induced voltage, ground voltage and the control waveform in real time. When checking suspected injector-control problems, KM50 provides clearer electrical data to help determine whether further injector or wiring diagnosis is needed
• 【Find and Verify Electrical Faults】Use the KM50 as a short circuit finder to track down shorts, identify open circuits, and check bad grounds, continuity and polarity. Then use component activation to apply power or ground to lights and compatible electrical components directly from the probe tip, helping narrow down whether further circuit or component diagnosis is needed before replacing parts
• 【Focused Diagnostics Made Simple】The included extension cable and long power cable provide added reach for different testing needs on 12V/24V vehicle electrical systems. Red/green LEDs, independently controlled lighting and buzzer feedback, a TFT color display and built-in overload protection make everyday electrical testing easier to follow for serious DIYers and independent technicians
