About this item

• Pro-Level All-in-One Automotive Power Circuit Probe Tester: ANCEL PB500 probe tester elevates the classic PB100 by integrating a Circuit Tester. Injector Driver. Oscilloscope. and Multimeter into one advanced diagnostic tool. Capable of handling 0–110V DC systems. it provides DC/AC Voltage Testing. Resistance and Diode checks. Continuity and Polarity Verification. Component Activation. Duty-cycle and Signal Analysis. plus Relay and Fuse testing. Built for efficiency. the PB500 tester electric helps technicians diagnose electrical issues faster and with greater confidence—reducing tool swapping and streamlining every step of the workflow.
• 7-IN-1 Advanced Test Modes: The PB500 circuit probe tester delivers more capability than standard testers. combining seven key diagnostic modes in one tool—DC Voltage. AC Voltage. Resistance. Diode. Frequency. Duty Cycle. and Fuel Injection testing. Switch between modes to match any troubleshooting scenario. quickly separate bad circuits from good ones. and dramatically speed up your diagnostic workflow. It helps you zero in on the true cause of electrical issues with clarity and confidence.
• Oscilloscope & Multimeter: PB500 allows you to switch smoothly between oscilloscope and multimeter modes. delivering clear waveforms and precise digital readings so you can diagnose with confidence. The multimeter offers fast. accurate measurements for Voltage(VDC). Resistance (OHM). Diode (DIO). Current (AMP). and Frequency. When you need deeper insight. the oscilloscope presents clean. real-time waveform graphs that instantly reveal signal fluctuations. Supporting AC/DC voltage. resistance. frequency. and duty cycle analysis. this advanced mode helps you verify sensor and actuator performance. detect weak signals. confirm circuit connectivity. and identify bad grounds with ease.
• Specialized Fuel Injection Tests: Struggling with the vehicle starting problems. poor acceleration. or fuel inefficiency? The he PB500 automotive circuit tester is fuel injection test Mode is designed for fast. precise diagnostics of the fuel injection circuit. It quickly analyzes the fuel delivery process. ensuring that each injector is firing precisely as it should. Plus. the addition of Frequency and Duty Cycle modes allows you to dig deeper into your vehicle’s performance. uncovering issues that standard diagnostic tools can’t detect. and giving you the insights you need to make accurate repairs and get your vehicle running at its best.
• Component Activation & Test: This automotive power circuit tester lets you activate and test on-board and off-board components with ease. It supports a wide range of vehicle systems. including blower motors. power window motors. windshield wipers. rear window defrosters. lights. radiator fans. and fuel injectors. By sending the required signal to each component. you can quickly determine whether it is functioning properly. Designed for both professional technicians and DIY enthusiasts. the tool works hand-held. in-vehicle. or with grounded connections. providing fast. accurate diagnostics and making electrical troubleshooting simple and reliable.
• Short-Circuit Tracking & Overload Protection: The PB500 circuit tester equipped with high-sensitivity probes. this ANCEL tester electric quickly tracks wiring issues and pinpoints short circuits or faulty wires to save serious troubleshooting time. Its resettable 10A circuit breaker protects both you and the vehicle by cutting power and sounding a buzzer when overload is detected. When tripped. the tool will not conduct battery current to the tip until reset—helping you avoid blown fuses and unnecessary repair costs.
• Quickly Identify Polarity & Highly Sensitive Probe: The ANCEL PB500 automotive electrical tools instantly checks component continuity and identifies positive. negative. and open circuits. When the positive terminal is connected. the red LED lights up with a beep; when the negative terminal is connected. the green LED illuminates with a low-pitched tone. Open circuits show no LED indication. Using red/green LEDs (active within ±0.8V) alongside the LCD display. the PB500 test light enables fast voltage detection—turning a simple polarity check into a reliable diagnostic tool.
