ANCEL PB100 汽车用品 Power Circuit Probe Tester, 12 24V Electrical Short/Open Breaker Finder, AC DC Diode Resistance Relay Tester, Continuity Test Digital Multimeter/Ohmmeters, 20 + 20FT Cable

【Quickly Identify Polarity & Highly Sensitive Probe】The ANCEL PB100 汽车用品 Circuit Tester 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 PB100 enables fast voltage detection—turning a simple polarity check into a reliable diagnostic tool.【Continuity & Signal Testing】The ANCEL Electrical System Probe Tester 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.【20FT Extension Cable & Cigarette lighter Plug】Unlike the ordinary power tester, ANCEL 汽车用品 Power Circuit Probe Tester comes with 20 feet long cord plus 20 feet extension cord.
