PB600 4-in-1 Automotive Power Circuit Probe Tester with True Waveform Oscilloscope, Battery Test, Injector & Relay Tester, Smart Multimeter Ohmmeter, 30ft Heavy-Duty Cable for Mechanic & DIY

Key Features

• All-In-One Automotive Circuit Tester — 20+ Diagnostic Functions — The ANCEL PB600 combines a Power Circuit Probe, Digital Multimeter, Oscilloscope, Battery Tester, Relay Tester, Injector Tester, and Component Activation functions in one professional-grade tool. Designed for 12V/24V vehicles, it provides 20+ testing and diagnostic functions to help technicians and serious DIYers troubleshoot electrical systems faster while reducing the need to switch between multiple tools.
• Oscilloscope + Digital Multimeter — Switch Modes Instantly — Easily switch between oscilloscope and multimeter modes with the press of a button. Monitor live waveforms and real-time digital readings for voltage, resistance, current, frequency, polarity, continuity, and more. The oscilloscope helps reveal signal abnormalities and intermittent problems that may be difficult to identify with basic electrical testers, making it useful for diagnosing sensors, injectors, ignition circuits, grounds, and other vehicle electrical systems.
• Check Battery, Starting & Charging Issues — Check key electrical conditions from the battery to the alternator to help diagnose starting and charging problems. The PB600 can assist in identifying weak battery conditions, abnormal cranking performance, charging-system issues, and other electrical problems that may contribute to hard starts or no-start conditions. A practical addition to both professional repair shops and home garages.
• Test Relays, Fuses & Fuel Injectors — Diagnose common circuit and fuel-system electrical problems with dedicated testing functions. Check fuse and relay circuits, evaluate injector signals, and investigate open circuits, poor connections, abnormal signals, and other electrical faults. The PB600 can help technicians troubleshoot misfires, no-start conditions, relay problems, and injector-related issues before replacing components unnecessarily.
• Component Activation & Test — Check Before You Replace — Activate and test components directly—like fuel injectors, radiator fans, power windows, lights, and more. Find faulty parts in seconds and avoid unnecessary replacements, saving time and repair costs. Whether you're working in your garage or doing quick checks on-site, this tool helps you diagnose problems step by step
• Extended 30ft Reach — Built For Large Vehicles & Hard-To-Reach Circuits — Go farther than ordinary power testers with a 10-ft main cable and 20-ft extension cable for up to 30 ft of total testing reach. Easily access electrical circuits and components throughout long vehicles, trailers lights, engine bays, and other hard-to-reach areas without constantly repositioning the tester.
• Dual Overload Protection — Auto Circuit Breaker + 10a Fuse — The ANCEL PB600 features a built-in automatic circuit breaker and 10A fuse for added protection during automotive electrical testing. The auto circuit breaker helps quickly interrupt the circuit in the event of an overload or short circuit, while the 10A fuse provides an additional layer of protection for the tester and vehicle electronics. Simply power up and test with greater confidence, no costly damage. Safety is not an option; it’s a built‑in guarantee.
• 10+ Years On Amazon — 100,000+ Orders In The Past Year — With over 11 years of automotive diagnostic experience, ANCEL has served Amazon customers for more than a decade. Backed by a 30-day refund and exchange policy, 1-year warranty, and professional customer support, we’re committed to providing reliable products and dependable service from purchase to everyday use.
