1、 It allows you to check the wires and cables of your car regularly without consulting the auto repair shop and spending a lot of money in the auto repair shop. 2、 This is an advanced instrument specially designed to track and identify wires and cables without placing the insulation layer in a damaged position. It can even track wire bundles effectively, even for internal bundles, ducts, behind panels, under carpets, upholstery, etc. You can quickly and easily find short circuits, disconnections, disconnections, leakage, and even wiring. 3、 The instant car circuit scanner is ready for 42 V because it is compatible with new vehicles with hybrid or single 42-volt systems. It has a transmitter with a receiver LED that displays open and short circuit conditions. It has adjustable sensitivity for all tracking processes. Just connect the wire harness of the tester to the line to be tested and start scanning, it can be easily achieved. 4、 The flexible probe helps to connect cables in crowded places and hard-to-reach areas. When you bend the cable or connector and hear the sound of the receiver change, you may also find intermittent circuit problems. 5、 Quick and easy, suitable for most types of vehicles. This is safe and accurate. So that the repair is quick. Material type: coiled steel Material type: electrical tester and test Wire material length: 8 inch Weight: 13.05 ounces Special function: short lead finder How to use: The probe of the probe receiver is made of spiral steel, which can be bent as needed to connect cables in crowded or difficult areas. According to the characteristics of the circuit and the sensitivity setting, the probe will pick up the signal from the cable within a certain range. However, in order to obtain the best range, the tip (black cap) of the receiver probe should be perpendicular to the wire under test and above or below it.
