Simply connect the tool to your vehicle's battery and you will be able to: ✅ Test voltage & polarity / continuity / signal circuits ✅ Activate components with hands, vehicle & ground ✅ Test trailer lights and connection✅ Find bad ground ✅ Find short circuits✅ Red/Green polarity LED
- 4 Advanced Working Modes: 4 advanced modes can be accessed by pressing the mode button to circulate each other: ☘DC Voltage: 0.1V resolution to read DC voltage. AC Voltage: Read the maximum value Voltage, Min. Voltage, Frequency, Duty Cycle Resistance: Read the resistance value between the tip and the auxiliary ground lead. Tone On/Off: Technicians use tones in dark environments to distinguish test results and turn off when not needed
- 👍【COMPANT ACTIVATION FUNCTION】Autel PS100 electrical system tester easily tests positive, negative, and open circuits. Also test continuity, diagnostic circuit failure, check for good and bad reasons, easy to read AC/DC current active components in and out of the vehicle, detect min/maximum voltage, etc. Autel Circuit Tester Automotive Tool can determine whether components are in good condition such as lights, motors, wipers, radiator fans, relays and more by generating a starting signal for components
- 👍【Quickly Identify Polarity and High Sensitivity Probe】Autel PS100 Automotive Circuit Tester instantly checks component continuity and identifies positive, negative, and open circuits. When you connect the positive terminal, the red LED light will light up and beep sound. Green LED lights up and bass when the negative terminal is connected. When open circuit, the LED light will not light up. In addition, the sharp stainless steel probe allows you to easily poke the wires and use them in tight and hard to reach areas
