Tools & Testers By AUTOOL

• Widely Applicable The AUTOOL BT210 power circuit probe tester is specially used for maintece and detection of 9-30V DC automobile circuits, which can quickly eliminate problems in the process of vehicle troubleshooting. Applicable to all types of vehicles, including automobiles, trucks, motorcycles, etc.
• Easy to Operate The circuit probe tester is easy to operate, and all operations can be completed with only two buttons. Briefly press the \"M\" key on the probe tester to switch five test modes. Briefly press the \"Lighting\" button on the probe tester to turn on or off the light beside the probe.
• Five Modes Optional Multi-function Mode: digital display voltage measurement, on-off test, positive and negative pole test. Voltage Test: digital display voltage measurement. On-off Test: can detect open circuit, path, virtual circuit and real circuit. Positive and Negative Pole Test: determine the positive and negative poles. Temperature Test: the pointer is equipped with a temperature sensor to detect the temperature of the specified contact.
• Excellent Design The design of this power short circuit probe is exquisite and compact, only 0.2 pounds, easy to carry and operate. The length of the wire is about 3.6 ft, which can cover the entire engine compartment and facilitate the inspection of the vehicle's electrical system. The high sensitivity probe with a tip makes it easier to touch small and difficult areas.
• Safety Protection The power short circuit probe has overload protection function. When the voltage or current is overloaded, the circuit tester probe will activate the overload protection function to protect the equipment and personnel..Lighting Setting The head of this car electrical system test tool kit is equipped with a lamp, which can work easily even in dark or weak light conditions.

• Widely Application This automotive electrical system test tool is the perfect choice for automotive circuit probe tester. Unlike other circuit testers that require you to use a variety of tools to troubleshoot electrical system problem, our circuit testers are perfectly capable of performing multiple types of services such as continuity testing, component activation, fuse test, checking bad ground indicator, detect voltage and current, positive and negative power supply.
• Portable Quick When the vehicle's headlights, turn signals, lift windows, sunroofs and other functions fail, our power circuit probe kit can output positive and negative power to check whether circuit components are normal, and can also perform continuity checks and resistance checks. Through these checks and diagnoses whether the path of the car circuit is interrupted, it can be found which parts of the circuit are intact, which parts are bad.
• Overload Protection Our automotive circuit tester tools has a built in 10 amp circuit breaker to prevent overloading and cooking a circuit.The output current can be reversed to form a loop power, and when the current exceeds 20A, This power circuit probe will automatically trip to protect the device and extend the service life.
• Humanized Design Built-in Flashlight enables you to work in the dark. Even in a dark environment where you can't see clearly, AUTOOL BT250 fuse tester automotive kit can give you a good view.
• LCD Color Display Modern and outstanding LCD high-definition color display. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. Moreover, the display screen is clearer, and the displayed data is more direct and clear.

• Why Need It The circuit breaker finder is mainly used to test the on-off condition of the automobile electrical system under the 6-24v DC voltage. When the fuse is blown due to a short circuit, using this circuit tester can help you quickly and accurately find the faulty wire and its fault point.
• Multi Functional Automotive electric system is test for continuity. Test for polarity of a voltage. Check switches, relays and the on-off of diodes, fuses and circuits . Test for polarity of electric cables and plugs. Track and locate short circuits. Test for bad ground contacts.Do not use on AC voltage.
• Easy To Use The circuit probe can be used to test and activate components in or out of the vehicle electrical system. Press button to Positive - side with LED lighting RED. Conact the probe tip to positive terminal of tested component to active the component. If LED turns to GREEN with buzzer, stop testing and check the component if defective or not, or rating current of component is higher than that of this tester.
• Widely Applicable The car circuit tester is suitable for the diagnosis of all 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, motorcycles, and airplanes. The portable and ergonomic design of the automotive circuit probe is convenient for you to use in narrow areas; the 4-meter extension cord is helpful for mobile maintenance work; the clip with strong bite force is not easy to fall off, providing you with a better experience.
• High Quality The circuit probe is equipped with overload power-off protection. If the current or load is too large during the power distribution process or When the current exceeds 7A, it will automatically disconnect to protect the battery and give a buzzer warning. With its short-circuit protection, you can test for bad ground contacts instantly. The insulation material used in this electrical tester has passed the CCC national safety compulsory certification, which is safe and reliable
• Three Years Warranty and Lifelong Maintenance For the damage caused by non-human factors, AUTOOL promises to resend the parts for free within 3 years. For any demand, we warmly welcome you to contact us, and we will reply you as soon as possible within 24 hours.

• Wide Test Applications:Voltage & Polarity Testing, Continuity Testing, Signal Circuit Testing, Activating Components in Your Hand, Activating, Components in The Vehicle, Activating Components w/Ground, Testing Trailer Lights and Connections, Checking for Bad Ground Contacts, Following & Locating Short Circuits, Red/Green Polarity LED.
• Four Work Modes: DC voltage mode is used to read DC voltage with resolution of 0.1 V, AC voltage mode is used to read Max. voltage, the Min. voltage, frequency and duty cycle, Resistance mode is used to read the resistance between tip and auxiliary ground lead, Tone On/Off mode is used to do a quick press of the mode button to toggle the tone on or off.
• Simple & Convenient: It will provide 20ft extendable cable for you to use. The long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.
• Humanized Design: Integrate LED flashlight on the head, let us work in dark condition easily. And it will indicate the test result on LCD Display for you to see clearly.
• No Worries: It can provide you maintain service when product main unit in bad condition without any destruction by external forces within 3 years. And it can repair the accessories since the day you receive the parcel within 1 year. No worry to return in 30 days. Our professional technical team will help you within 24 hours if you have any problem when you use it.
