DUOYI DY25 Automotive Short and Open Circuit Finder Wire Locator Tester Car Repair Tool Tracer Diagnosis Cables/Wires Packing list DY25 sender 1 pieces DY25 receiver 1 pieces User manual 1 pc. (in English) Oxford bag 1 pieces Quickly and easily locate short circuits Save time and increase your income Evaluate the continuity of cables or wires. Track cables or wires and diagnose breakpoint Receive an audible signal on cables or wires (phone line) The DY25 detects and alerts you immediately where the circuit is open. You can quickly and easily locate short circuits, open connections, damaged wires, current leaks, and even trace wires. You can also find intermittent circuit problems by bending wires or connectors and listening to change the tone of the receiver, allowing you to generally track or indicate the location of the problem. It also shows the direction of the shortcut using turn signals, eliminating guesswork. This professional tool will work on all types of circuits with voltage from 6 to 42 v DC. Such as those found in cars, trucks, tractors, boats, RVs, etc. with a wide operating voltage range This instrument is designed to identify and track wires or cables without damaging the insulation. It can also be used to check short circuit and loacting open circuit and so on. The instrument has a sender and receiver. 225mm 1. Tracing wire 2. Short-circuit checking 3. Locating an open circuit 4. Wire Identification Function * Wire tracking is possible even inside bundles, wires, behind panels, under carpets, upholstery, etc. * Easy to use: simply connect the transmitter in series with the circuit or cable being tested (i.e.: instead of a burnt fuse, through the connector, in series with an open cable, light bulb socket, etc. ), and scanning the circuit/wire with a flexible tracers probe to find a place of trouble * 42 V Ready: for use in a new generation of vehicles with mixed or single 42-volt systems * Operates on DC voltages from 6 to 42 volts * Internally protected against surges and overloads * 7" flexible probe allows you to reach wires in crowded areas * Transmitter and receiver leds show opening or short circuit conditions * Adjustable sensitivity for all tracking situations * Wire-free piercing required, touchless technology! The receiver probe is constructed of coiled steel and can be bent as needed to reach wires in difficult or challenging areas. Depending on the circuit characteristics and sensitivity settings, the probe will receive the wire signal in different positions. However, for the best possible range, the receiver probe tip (black nut) should be positioned perpendicularly (at a 90° angle) to the wire that is tracked and above or below it. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
