1. Portable Multifunctional Electrical Tester The 4-meter extension cord is helpful for mobile maintece work and is suitable for diagnostics of all 6V to 24V automotive electrical systems. The tester is made of ABS material, which is moisture-proof, high-temperature resistant, impact-resistant and has a longer service life. The tester also has an overload protection device, When the current exceeds 7A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt.
2. Polarity Test and Continuity Test The tester is made of insulating material and high-quality stainless steel, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug. When the tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The electric circuit tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits.
3. Component Activation and Testing For professionals or car enthusiasts, this continuity tester is a great tool. The automotive short circuit tester can activate the components in/out of the vehicle's electrical system. The LED indicator and buzzer prompt can easily test and check whether the components are defective, or whether the rated current of the component is higher than the rated current of the tester.
4. Automotive Circuit Tester for Grounding Test The design of the circuit breaker finder is perfectly designed and feels comfortable. It is equipped with a 4M extended detection line, covering the front to the rear of the vehicle and easily detecting the entire vehicle circuit system. The automotive circuit tester kit has a grounding prompt device. If the LED indicator turns green and the buzzer sounds, it means that the grounding is good. If it is not, the LED remains red and there is no beep.
5. Tracking and Locating Short Circuits The electrical tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using the continuity tester can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point..6. 24-Hour Service and 1-Year Warranty We provide this circuit probe tester with 24 hours friendly customer service and 12 months free warranty to ensure your shopping experience.
