And you will hear different beeps when testing on different polarity.
- 【Following & Locating Short Circuits】In most cases, a short circuit will appear as a blown fuse or a tripping of an electrical protection device. Use the probe tip to activate and energize each of the fuse contacts. The contact which trips the circuit breaker is the shorted circuit. While Autel short finder probe can test for bad ground contacts instantly, allowing you to follow and locate shorts fast without wasting fuses.
- 【Continuity Tests & Signal Tests】Put the Autel powerscan circuit tester in Resistance mode, using the probe tip with chassis ground or the auxiliary ground lead, continuity can be tested on wires, switches, relays and diodes attached or disconnected from the vehicle electrical system. Signal Circuit Test can be useful when you extract a DTC from the vehicle and realize the cause might be kind of sensor circuit, testing your sensor and you will find the answer.
- 【Activating Components】This Autel PS100 auto circuit tracer kit can activate components in vehicle, in hands, and with ground, satisfying all the working scenarios. Autel circuit tester can generate activation signals to the tested components, such as activating lights, motors fans, wipers and other on-board electric equipment. Autel circuit probe kit can also find bad ground contacts, by observing the response of the LED lights, you can tell whether it's true ground.
- 【40ft Test Wiring, Bright LED Lights】Autel PowerScan PS100 automotive electrical tester comes with a 20feet long cable and another 20ft extension cable that allows you to make the initial connection directly to the vehicle's battery whether how large the vehicle/ tractor is, you can have easy accessibility to connect the trailer effortlessly to the rear of the vehicle. And on the top of the tester, there is a built-in flashlight, illuminate your work in dark or night, making you detect faults effectively.
- 【4 Working Modes】Autel Probe PS 100 electrical circuit tester has 4 working modes to diagnose the electrical systems. In DC Voltage mode, it will read the DC voltage with a resolution of 0.1 volt. In AC voltage, it 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.
- 【2025 Newest PS100 Circuit Probe Tester】Autel Powerscan PS100 circuit probe tester has more functionality than a multimeter. It is needed for Circuit Test, Continuity Test, Electrical Component Test, Ground Contact Test, Locate Short, Activate Component, Voltage & Polarity Test, Trailer Lights and Connections Test and etc. For example, you can use it to turn on a blower motor, windshield wipers. You can check system failure without efforts yourself with this electrical system diagnostic tool.

KAIWEETS Voltage Tester, Non-Contact Voltage Tester with Signal Percentage, Dual Range AC 12V/70V-1000V, Live/Null Wire Tester, Electrical Tester with LCD Display, Buzzer Alarm, Wire Breakpoint Finder
Free ShippingMain highlights- SAFETY FIRST: IEC-rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red, and the safety symbol on the screen shines.
- NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners.
- EASY USE: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, and green means low voltage and null wire are detected.
- DUAL-RANGE: Detects standard and low voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph, and the percentage value can display the voltage signal intensity more intuitively.
- COMPACT DESIGN: Bright LED flashlight for work in dim areas; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket. KAIWEETS provides a 3-year after-sale service, Please feel free to contact us if you have any concerns.
