- 【2025 New Autel Circuit Tester: PowerScan PS100】The launch of Autel PowerScan PS100 is to offer quick complete diagnose solution for all 6- to 30-volt vehicle electrical systems, featuring AVOmeter, test light, built-in flashlight, short circuit indicator, relay/component tester, continuity tester and bad ground indicator, the PowerScan is powerful yet affordable, allowing users to check circuitry in one single step. A good-to-have tool for technicians.
- 【Easy Switching 4 Working Modes】Autel PS100 Power Circuit Probe Kit support four working modes: DC voltage, AC voltage, Resistance and Tone On/Off. In AC voltage, PS100 can read the Max. voltage, the Min. voltage, frequency and duty cycle; In Resistance mode, it reads the resistance between the tip and auxiliary ground lead. In Tone On/Off, you can turn off the annoying noise when the tool will be connected to circuits for a long time. Quick switching among 4 modes by pressing mode button.
- 【Compnent Activation Function】Autel PS100 support component activation in 3 different scenario: in the hand, in the vehicle & with ground. By generating activation signals for the components, you can judge whether the components are in good condition, such as lights, motors, wipers, radiator fans, relays, and fuel injectors, etc. You can also use Autel PS100 circuit checker to find bad ground contact. The response of LED lights can intuitively tell you whether it's true ground.
- 【Polarity Quick Identification】In just a few seconds, Autel PS100 can checks component continuity and identifies positive, negative and open circuits. When the positive terminal is connected, the red LED light is on, accompanied by a beep. When the negative terminal is connected, the green LED lights up, along with low pitched tone. If it is an open circuit, the LED light will not light.
- 【Overload Protection & Quick Self-Test】Autel PowerScan PS100 is short-circuit protected. Its internal circuit breaker will trip if it becomes overloaded. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload. To protect your components, Autel PS100 can also perform a quick self-test. After flipping the switch forward or backward, the LED light and tone will respond to quickly check its actual operating status.
- 【Built-in Flashlight & 20ft Extension Cable】Autel PS100 comes with built-in flashlight for convenient detection in dark or at night. The 20 feet extension cable ensures provides excellent accessibility to test along large vehicles and the entire circuit system of the vehicles can be tested at ease.

20 feet cable plus Extra 20ft Extension Cable for Large Vehicle Testing
Autel PS100 comes with exta 20ft (extendable) cable that provides excellent accessibility to test along large vehicles and the entire circuit system of the vehicles can be tested at ease.
Two Power Supply Methods for Autel PS100 Circuit Tester:
- 1. Vehicle battery power supply
- 2. Ciga-rette li-ghter power supply
How to Perform Quick Self-Test :
- Before you test a circuit or component, be sure your tool is in good order by doing a quick self-test.
- With the tool connected, perform a quick self-test. The power switch is a momentary rocker switch located on the tool's body. Flanking the switch are positive and negative markings.
- Press the Power Switch forward to activate the tip with a positive voltage. The Red LED should light and the LCD display will read the battery voltage. If the tone feature is turned on, a high pitched tone will sound. Let go of the power switch and the LED will turn off and the high tone will cease.
- Press the Power Switch rearward to activate the tip with a negative voltage. The Green LED should light and the LCD display will read the „0.0V‟ (ground). If the tone feature is turned on, a low pitched tone will sound. Let go of the power switch and the LED will turn off and the low tone will cease.
