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.

20ft Extension Cable:

Autel automotive electrical tester comes with extra 20ft extension cable in addition to its own 20ft cable, allowing you to access any position of the vehicle and test it. Ideal for trailer wiring, it can be tested along the vehicle without having to find a suitable ground point. The built-in flashlight is convenient for detection, even in the dark or dim environment, it can provide the best view for who need to work in night.

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.

Autel PowerScan PS100 with Wide Coverage:

Autel PS100 Automotive Circuit Teste can be used to test almost all 12V-24V electric devices including motorcycle, motorboat, large trucks and so on. Autel PS100 is a must have tool for every technician looking for a fast and accurate solution to electrical system diagnostics.
