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....
