LOW VOLTAGE INDICATION: The automotive open & short finder tool available on the market may exhibit inaccurate test results when the battery is low. In response to this issue, we have upgraded the transmitter and receiver, making both of them capable of providing low battery alert functionality. So, you will no longer be affected by the low battery condition, and the test results will be more accurate.
SOUND AND LIGHT INDICATION: Have you ever encountered a situation when using the wire tracer in a noisy environment, and the noise made it difficult for you to distinguish the lines? Our wire locator with sound and light indication function is definitely your new best choice. Don't worry about the noise issue. Through sounds and LED indicator lights, it can clearly, quickly and accurately indicate the situation of the lines.
CONTINUITY FUNCTION: Push the transmitter switch upwards to the CONT mode, and attach the red and black clips to both ends of the wire under test respectively. If the wires are in good condition, the green light will come on. If it doesn't light up, it indicates that the wire is faulty.
