Feature 1Short Circuit Detection: Wire detector can allow you to quickly and easily find short circuits, open connections, broken wires, current leaks and even trace wires. 2Intuitive Display: Transmitter and receiver LEDs show open or short circuit, giving you a visual and direct observation. 3Flexible Probe: 7in flexible probe allows to reach wires in crowded areas, making your detection faster and making the process easier. 4Safe Performance: Automotive short circuit detector operates at 6 to 42 volts DC with internal protection from surges and overloads. 5Advantages: Adjustable sensitivity for all tracking situations, and comes with a storage bag for easy carry and use.Item Type:AutomotiveCircuitTesterMaterial: ABSVoltage: 6-42V DCPower Supply: 2 9V batteries (not included in the package)Function:Tracing of wires is made possible even inside bundles, co nduits, behind panels, under carpets, upholstery, etc .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Easy to Use: Simply connect the transmitter in series with the circuit or wire under test, (i.e: in place of a blown fuse, across a connector, in series with an open wire, a light bulb socket, etc.), and scanning the circuit/wire with the tracers flexible probe to find the trouble spot42 V Ready: for use in the new generation of vehicles with mixed or single 42 Volt systemsOperates on DC voltages from 6 to 42 voltsInternally protected against power surges and overloads7in flexible probe allows reaching wires in congested placesTransmitter and receiver LEDs show open or short circuitConditions:Adjustable sensitivity for all tracing situationsNo wire piercing required, non contact technology!Hpw to Use The Probe?The probe of the receiver is built of coiled steel and may be bent as needed, in order to reach wires in ongested or difficult areas. Depending on the circuit characteristic and sensitivity settings,the probe will pick up the signal from the wire in a range of positions. However, for the best possible range the Receiver's probe tip (black cap) should be positioned perpendicular (at 90) to the wire being traced and either above or below it.Package List1 x AutomotiveCircuitTester1 x Battery Clip Box1 x User Manual1 x Storage Bag
