Description: The EM415PRO detects and instantly alerts you to the location of opens in circuits. You can quickly and easily find shorts, open connections, broken wires, leaks and even trace wires. You can also find intermittent circuit problems by bending the wire or connector and listening for the change in the receiver tone, allowing you to do a general trace or pinpoint the problem location. It also shows you the direction of the short with a direction indicator, eliminating the guesswork. This professional tool works on a variety of circuits with voltages between 6 and 42 volts , such as cars, trucks, tractors, boats, RVs, etc Wide range of operating voltages Quickly and easily locate shorts Save your time and increase your revenue Determine the continuity of a cable or wire. Trace cables or wires, diagnose breaks Receive a tone signal on a cable or wire (telephone line) Identify the status of a working phone line (clear, ringing, busy) Send a single solid tone or double alternating tones to the subject cable or wire. Product Details Power Supply: Two 9V Batteries (Not Included) Product Width: 4 cm Material Type: Coiled Steel Product Height: 15 inches Product Type: Electrical Tester and Test Leads Product Length: 17 cm Special Features: Short Cable Detector About the Product This instrument is designed to identify and trace wires or cables without damaging the insulation. You can also use it to check for shorts and locate opens, etc. The instrument contains a transmitter and a receiver. Specifications 1. Line Tracing 2. Check for Shorts 3. Locate Opens 4. Line Identification Features * Trace lines even in wire bundles, conduits, behind panels, under carpets, upholstery, etc. * Easy to Use: Simply connect the transmitter in series with the circuit or line under test (i.e.: in place of a blown fuse, jumper connector, in series with an open circuit, light bulb socket, etc.) and scan the circuit/line with the tracer flexible probe to find the point of trouble * 42 V Ready: For vehicles with new generation single 42 V systems * Operates on 6 to 42 V * Internally protected against surges and overloads * 7-inch flexible probe allows access to lines in crowded places * Transmitter and receiver LEDs indicate open or short conditions * Adjustable sensitivity for all traced conditions * No need to pierce wires, non-contact technology! How to Use the Probe? The receiver's probe is made of coiled steel and can be bent as needed to reach wires in crowded or difficult areas. The probe will pick up signals from the wire at a range of locations, depending on the circuit characteristics and sensitivity setting. However, for best range, the receiver's probe tip (black cap) should be placed vertically (90o) above or below the wire being traced. Package 1 x Automotive Shorts and Opens Detector
