[WIDER VOLTAGE RANGE] Compared with the auto electrical tester on the market, the maximum voltage measured is only 48V, but the maximum voltage that our technology can measure is upgraded to 60V. AWBLIN circuit test is ideal for checking various vehicles electrical circuits, quickly check automotive headlights, taillights, turn signal circuits, faulty sockets, fuse connections, also for testing other 3-60V DC wirings and circuits.

[LED INDICATION, BIDIRECTIONAL VOLTAGE TESTING]: This upgrade circuit test light is a bidirectional voltage tester. You can attach the alligator clamp either to negative or positive ground, there is also a light emitting diode on the circuit board for polarity indication, Red light indicates Negative polarity and Green light indicates Positive polarity.

[COMPUTER SAFE, DURABLE & FLEXIBLE]: The professional auto circuit tester has a built-in circuit board chip, which is safer and more durable than traditional test lights and prevents the car computer board from burning out. Spring wire can be freely stretched up to 102 inches, with a wide measuring area; Anti-bending design of the tail wire, no need to worry about bad contact of the line.

🚘Power Probe Master Kit is an essential tool for automobile user. It is needed for testing components on and off the vehicle, checking for the good and bad grounds, testing for continuity and diagnosing circuit failures. If the vehicle owner keeps it in his car he can check system failure on his own way no need to go to technician.

🚘[The Main Function]: The P100 Power Circuit Probe Kit is mainly used to test car battery voltage, AC and DC voltage test, resistance, leakage, short circuit, component activation overload protection and other car circuit system problems. Auto circuit tester with large battery clip, can carry more load. Support wide input voltage range from 9V to 70V, also support 12V cars and 24V trucks.

🚘[Working Modes & Easy to Diagnose]: Easy to navigate user menu allows reading DC Voltage, AC voltage, Resistance and Diode parameters very clear. A quick self-testing is a must before to test a circuit or component, ensure your tool is in excellent condition.

🚘The P100 Pro is the newest generation intelligent electrical system circuit tester with 2.4-inch large-size LCD screen display. It is dedicated to testing all 9V-30V vehicle electrical systems. P100 Pro is convenient, fast and Intelligent, hence saving you time and money. This would make a great Christmas gift for men/dad!

🚘【Intelligent Multimeter】TopDiag P100Pro automotive electrical tester not only has a multimeter mode (measure voltage/resistance, diode test) can also test trailer lights, AC circuit signal test, vehicle component activation, etc.

🚘【Safe and Reliable】 This circuit tester unit has a short circuit protection function, which can instantly detect poor ground contact and find the short circuits. It also has a (0-5V) adjustable power supply, which can adjust the voltage output below 5V and limit the current below 100mA to protect your electrical components.

[PACKAGE]-This electrical alligator clips tester includes 20pcs = 5 colors * 4pcs alligator clips, which the alligator clip wires length is about 19.3 inches, wire clips length: 1.38 inches. This alligator clips set for HVAC come in multiple colors so you can distinguish between connections when working on a project. And now this double ended alligator clips electrical kit can be used widely in electronic experiments, breadboarding, prototyping, trouble shooting, circuit connection, etc.

[FLEXIBLE & DURABLE]-This test leads with alligator clips cover is made of high quality soft PVC, which make this test leads set have great flexibility. So, this electrical test leads is not easy to break after repeated usage. And this gator clip adopted high quality spring, which make this alligator clip leads has strong and solid clipping. So, alligator test leads is not easy interrupted during the testing. Therefore, this alligator clamp can be durably and safely used in daily electric work.

[GOOD PERFORMANCE]-This alligator clip jumper wire adopts high quality copper wire and pure metal clip, well constructed and have a sturdy wire attached. The wire firmly crimped to the steel clamp, so, this jumper wires with alligator clips has the great conductivity, ensure the test accuracy. What's more, its outside was covered by vinyl sleeve which made this electrical jumpers has insulation and protection ability. NOTE THAT, please DO NOT over the rated voltage for this metal alligator clip.

1.[ Voltage Tester For Car For Circuit Fault Detection And Maintenance ]: This dc power tester is mainly used for low-voltage circuit fault detection and maintenance. It is mainly used for the testing of automotive circuits. It cannot be used for testing household circuits.

2.[ Low Voltage Circuit Tester For 6V V V DC Voltage ]: The DC voltage test range of this circuit tester is mainly low voltage of 6v v v. NOTE: The tester cannot be used for AC voltage.

3.[ Hook Probe Electrical Tester ]: The voltage tester has a unique hook probe design. Users only need one hand to find and fix the circuit under test more conveniently. Just gently pull the handle, you can use the probe to pierce the insulation and touch the copper wire. This makes the detection more convenient and faster. NOTE: Please do not use this tester to test a thick wire, so as not to be unable to test and lead to inaccurate test results.
