All-in-One Automotive Electrical Tester - Integrates 10+ practical test modes including leakage current detection, fuel injector test/cleaning, 0-5V power supply, positive/negative test, smart test, multimeter, oscilloscope, relay test and component activation, meeting all your vehicle electrical system testing needs in one tool
Wide Voltage Compatibility & Precise Measurement - Works with 9V-48V vehicle electrical systems (ideal for 12V/24V cars, trucks and more); Boasts high-precision measurement with 2mV-99.9V voltage range, 0.01Ω~10MΩ resistance range and 2mA~100A current range, with 320*240 DPI 2.4-inch color LCD for clear and intuitive data display
Multiple Safety Protection Designs - Built-in 25A fuse and automatic short-circuit circuit breaker protection (adjustable current 1A~100A) to prevent overload and short circuit damage; The 0-5V power supply mode limits current under 100mA to avoid burning out sensitive electronic components, ensuring safe operation for both the tester and vehicle
Easy to Operate & Humanized Details - 6 physical navigation buttons for quick mode selection and parameter adjustment; Front LED light for convenient operation in dark working areas; Supports hibernation mode, multi-languages, online firmware update and 30-minute continuous leakage current recording with playback function, making testing efficient and hassle-free
Versatile Test Applications - Perfect for continuity test, signal circuit test, bad ground contact check, short circuit locating, trailer light/connection test, and activating on-hand/on-vehicle components (lights, motors etc.); The probe tip can pierce plastic wire insulation for non-destructive testing, suitable for professional mechanics and DIY car enthusiasts
