Ancel Circuit Tester PB500

The Ancel PB500 is a professional-grade, portable circuit tester designed for quick, accurate diagnostics on 12–24V vehicle electrical systems. Its color TFT shows live readings and simplifies troubleshooting across seven essential modes: DC and AC voltage, resistance, diode check, frequency measurement, duty-cycle analysis and injector circuit testing. Use it to trace shorts, open circuits, bad grounds, faulty injectors or erratic sensor signals without disassembling wiring looms.

Key features:
• Wide vehicle coverage — works with cars, trucks, motorcycles and boats operating on 12–24V systems.
• Seven diagnostic modes — versatile set replaces several single-purpose tools.
• Real-time TFT readout — clear numeric and graphical feedback for faster localization of faults.
• Safety — overload protection guards the tester and vehicle circuits against incorrect connections.
• Practical aids — LED probe tip for working in dark engine bays and a probe extender for hard-to-reach points.
• Robust workflow — simple button layout speeds measurements in workshop conditions.

Typical uses:
• Measure DC/AC voltages and confirm charging/ignition circuits.
• Check continuity and resistance to detect broken wires or poor contacts.
• Verify diodes and sensors, measure frequency and duty cycle for pulse-based components (e.g., injectors, hall sensors).
• Rapid injector circuit checks to spot wiring faults or driver issues.

Package contents: circuit tester, battery cable with terminals, probe extender, probe tip, diagnostic hook and extension cable, protective case, instruction manual. The PB500 is aimed at professional technicians and DIY enthusiasts who need a single, fast tool for everyday electrical diagnostics.
