ANCEL PB500 汽车用品 Power Circuit Probe Tester, 12/24V Circuit Breaker Finder, with AC/DC, Diode, Resistance, Frequency, Injector, Duty Cycle, Multimeter, Oscilloscope, Ohmmeters Test, for 99% Cars

【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 汽车用品 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.【Continuity & Signal Testing】The ANCEL 汽车用品 short circuit finder quickly checks sensor operation and accurately verifies circuit continuity. It offers two easy testing methods: 1. Resistance Mode – A reading of 0.0Ω with the LED on confirms continuity; “OL” indicates an open circuit. You can even pierce wire insulation to test without disconnecting; 2. Power Switch Method – Apply power to the circuit; if the breaker trips, it signals low resistance and confirms continuity. Perfect for diagnosing broken wires, checking ground quality, and troubleshooting vehicle electrical systems with speed and confidence.【Dual Headlights & Intuitive Backlit LCD Display】To be a proper solution for nighttime testing jobs, the PB500 汽车用品 electrical tester comes with a lighting function to support your testing needs in a low-light environment. What's more, this PB500 circuit tracer with highly clear LCD digital backlit display screen, a resolution of 0.1V, clear & visible digital readouts for day and night. Easy to read AVOmeter allows you to read voltage, current and resistance at the fingertip.【Top-Ranked 汽车用品 Electrical Tester】The ANCEL PB100 electrical circuit tester is one of the most versatile 汽车用品 electrical tools on the market—highly recommended by auto electrical specialists worldwide.
