About this item

• ★ [Function of Continuity Testing] The Continuity Test primarily determines if the circuit is energized and if there is a short circuit present. Once the circuit tester is properly connected, attach the auxiliary grounding wire to one end of the test line and place the probe tip on the opposite end. A continuous circuit will light the LED green. If the LED remains off, it indicates that the circuit is not powered.
• ★ [Circuit Tester has fast self-test and overload protection] Circuit tester can set 6-24V output voltage for verifying the wiring conditions of the test component, and the device can make quick self-test before testing circuits or components.
• ★ [Very professional test tool] This circuit tester can test uncertainties in the vehicle circuit. Perfectly perform each function, such as continuous testing, polarity testing, jumper operation, short-circuit tracking positioning, etc.
• ★ [Beep Alarm and LED Light Indication, High Securities Probe] Circuit Tester adopts advanced high-sensitivity probes and clips, can quickly and accurate testing, provide a better experience. There is also a LED indicator and buzzer warning to provide a clearer and clear help during the testing process.
• ★ [Positive Negative Negative Test Function] Electrical Tester is used to test uncertainties in the vehicle circuit, and connect the red clip to the positive electrode of the vehicle battery. Connect the black clip to the negative electrode of the battery. When the tip of the probe is in contact with the positive electrode (+), the LED should illuminate Red. Contact the tip of the probe (-), the LED should be green.
