Amprobe UAT-620 Underground Utility Locator Kit with Clamp

[Multifunctional Circuit Tester] The circuit tester can quickly and efficiently test all 6V to 24V car circuit systems, and is the best tool to shorten the diagnosis time of automotive circuit systems. It is perfectly for polarity test, continuity test, components test, jumper lead operation, grounding test, short circuit following and locating, etc..
[Polarity Test & Continuity Test] When the polarity of the circuit under test is unknown, this circuit tester can help you quickly identify the positive and negative poles of the circuit, and whether the circuit is in a continuous state or an open state. The red light is on when the probe tip is in contact with the positive pole or the circuit is open, and the green light is on when the probe tip is in contact with the negative pole or the circuit is in a continuous state..
[Component Test & Diode Test] Contact the probe tip to the positive terminal of the tested component to active the component. It can detect whether there is a large current flowing through the element and whether the negative electrode of the detection element is well grounded. Quickly test diode assembly operation and determine if circuits are opened or continuous. When the grounding is good, the green light will be on and a "beep" wi....

Fluke BT510 Battery Analyzer

[ Polarity Testing & Continuity Testing ]: The power circuit probe tester can be used to test uncertain contact polarity in vehicles. When the it touches the positive pole, the indicator light will turn on red, and when it touches the negative pole, it will turn on green. In addition to polarity testing, the power short circuit finder can also perform continuity testing, it is mainly to test whether the circuit has continuity and whether it is short-circuited..
[ Quickly Tracking and Locating ]: The circuit tester is mainly used to test the on-off condition of the automobile electrical system under the 6-24V DC voltage. In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. 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..
[ LED Indicator& Buzzer Dual Warning ]: In order to let you understand more intuitively and clearly understand the grounding of the components, the power circuit probe tester comes with an LED indicator and a buzzer. The test light can perform a quick self-test to ensure your tool is in good condition. When the current exceeds 7A, the circuit tester will disconnect the curren....
