Support✅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 or 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 Modes—Quick& Accurate】4 modes via Mode Button. Just Contact probe to circuit, LCD instantly displays results: 1️⃣DC voltage: read the DC voltage with a resolution of 0.1 volts. 2️⃣AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle, shows the modulation from the ECM to an Alternator wire to see if the ecm is commanding the alternator on. 3️⃣Resistance: read the resistance between the tip and auxiliary ground lead, you can clearly check fuse/line continuity, pinpoint open circuits & verify switch functions. 4️⃣Tone On/Off: it can indicate the tester's on/off status, You can turn it off to avoid ear interference from noise during testing. - 👍【Compnent Activation Function】Autel PS100 Electrical Fuse 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 Tester & Signal Circuit Tester】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, view live Max/Min voltage, frequency, and duty cycle on the LCD to confirm proper function. - 👍【Short Circuit Troubleshooting & Built-In Overload Protection】As a good relay tester, 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. - 👍【Quickly Identify Polarity & Highly Sensitive Probe】Autel PS100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative and open circuits. When the positive terminal is connected, the red LED test light is on, accompanied by a beep. When the negative terminal is connected, the green LED is on, along with low pitched tone. If it is an open circuit, the LED light will not light. By using red/green LEDs (illuminated only within ±0.8V) alongside the LCD reading, the PS100 provides quick voltage drop detection—turning a simple polarity check into a reliable diagnostic tool. The sharp stainless steel probe easily pierces wires and reaches tight areas. - 👍【20FT Extension Cable & Cigarett.e lighter plug—Convenient】Unlike the power probe, Autel PS100 Automotive Power Circuit Probe Tester comes with 20 feet long cord plus 20 feet extension cord. Combining the feature that it can be powered by the ci*gare.tte li*ghter, and alligator clip for convenient ground connection, you can test electrical circuit system anywhere around the longer vehicles and trailers. Extra cigarette lighter plug, no need to open the hood to connect the battery, so you can easily and quickly conduct in-vehicle circuit testing - 👍【Dual Head Lights & Intuitive LCD Backlit Digital Screen】To be a proper solution for nighttime testing jobs, the Electric Test Pen of PS100 Wire Tester comes with a lighting function to support your testing needs in a low-light environment. What's more, this PS100 Circuit Light Tester 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BW48DKFG | | Best Sellers Rank | #8,722 in Automotive ( See Top 100 in Automotive ) #56 in Code Readers & Scan Tools | | Brand Name | Autel | | Color | Rose | | Customer Reviews | 4.7 4.7 out of 5 stars (405) | | Included Components | 1 X Circuit Tester | | Item Dimensions | 1.18 x 1.18 x 0.39 inches | | Item Type Name | Autel Powerscan Circuit Tester | | Manufacturer | Autel | | Measurement Type | Multimeter | | Minimum Operating Voltage | 12 volts_of_direct_current | | Model | A-M017-00-US | | Part Number | Autel Circuit Tester | | Power Source | Battery Powered | | Specification Met | UL | | Style Name | Circuit Testers | | UPC | 849438026639 | | Upper Temperature Rating | 60 °C | | Warranty Description | 1 Year Warranty By the Manufacturer | ## Product Details - **Brand:** Autel - **Color:** Rose - **Item dimensions L x W x H:** 1.18 x 1.18 x 0.39 inches - **Power Source:** Battery Powered - **Style:** Circuit Testers ## Images ![PowerScan PS100 Circuit Tester 2.0, 12-24V Power Circuit Probe Tool | Electrical Short Open Circuit Finder, AC/DC/Resistance/Component/Signal/Test Light Automotive, 20ft Extension Cord - Image 1](https://m.media-amazon.com/images/I/71tDvoq1M4L.jpg) ## Questions & Answers **Q: This unit came with plastic case and extra extension cord?** A: Hello there, Yes, Autel PS100 power Circuit probe kit comes with rugged blow molded case and extra 20FT extension cord (Total 40FT).
