Autel PowerScan PS100 Automotive Circuit Tester 2.0, 12-24V Power Circuit Probe Tool, Auto Electrical Short Open Circuit Finder, AC/DC/Resistance/Component/Signal/Test Tool, w 20ft Extension Cable

👍【2025 Autel Power Circuit Probe Kit US Ver 2.0】Autel PowerScan PS100 is the best Electrical Tester for reducing diagnostic time in all 6—30V vehicle electrical systems. Supports✅Test Voltage & Polarity/ Continuity/Signal Circuit✅Activate Components in Your Hand/in the Vehicle/ w/Ground✅Test Trailer Lights and Connections✅Tracking Short& Open circuits✅Find Bad Ground✅Circuit Breaker Overload Protection✅Red/Green Polarity LED & Voltage Drop✅20ft +20ft cable. Compared with test lights and multimeters, PS100 provides faster, intuitive diagnosis with extended data display (AC/DC, resistance, diode) while also enables component active testing and short circuit tracing through its circuit breaker
👍【4 Advanced Working Modes—Quick& Accurate】4 advanced modes can be accessed by depressing the Mode Button and cycling through each one: ➊DC voltage: read the DC voltage with a resolution of 0.1 volts. ➋AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle. ➌Resistance: read the resistance between the tip and auxiliary ground lead. Using the Autel PS100's resistance mode, you can quickly and clearly check fuse/line continuity (with visual and audible feedback), pinpoint open circuits (seeing "OL"), and verify switch functions. ➍Tone On/Off: technicians use the tone in a dark environment to distinguish the test results and turn it off when unnecessary.
👍【Compnent Activation Function】Autel PS100 Electrical System Tester will test the positive, negative, and open circuit easliy, also testing for continuity, diagnosing circuit failures, checking good and bad grounds, easy to read AC/DC current activating components on and off the vehicle, sensing MIN /MAX voltage, etc. By generating activation signals for the components, Autel Circuit Tester Automotive Tool can judge whether the components are in good condition, such as lights, motors, wipers, radiator fans, relays, etc. No jumper wires are required, making the process of diagnosing your car's circuits safer, faster, easier, and less prone to error.
👍【Pro Continuity & Signal Circuit Test】PS100 easily locates wire breaks and checks ground quality.1️⃣ Resistance Mode: Connect the probe tip and ground lead. A solid connection reads “0.0Ω” with a green LED. “OL” means an open circuit. You can even pierce insulation to test without disconnecting wires.2️⃣ Power Switch Method: Applies voltage to check for ultra-low resistance—great for ground tests. What to do when faced with reading a DTC to learn that a sensor may have a problem? 📶Signal Test: In AC mode, connect to the sensor’s signal wire and ground. As you operate the sensor (e.g, apply vacuum), view live Max/Min voltage, frequency, and duty cycle on the LCD to confirm proper function.
👍【Short Circuit Troubleshooting & Built-In Overload Protection】The PS100’s resettable circuit breaker helps quickly locate short circuits—just apply voltage along the line using its highly sensitive probes to pinpoint the issue, saving both fuses and money！ A built-in 10 Amp breaker also protects against overloads, cutting power and sounding a buzzer if limits are exceeded. The circuit breaker will trip if it becomes overloaded to protect the battery and give a buzzer warning. When the circuit breaker is tripped, the Electrical Probe Tester will NOT be able to conduct battery current to the tip even when the power switch is pressed—until it resets.
