                        Testing:
                        1.Polarity Testing
                        This tool can test uncertain polarity of contact in the circuit of vehicle.
                        -Unroll the leads
                        -Connect red clip to positive terminal of vehicle's battery.
                        -Connect black clip to negative terminal of vehicle's battery.
                        -Contact the probe tip to a positive (+), the LED should light RED.
                        -Contact the probe tip to a negative (-), the LED should light GREEN.
                        2. Continuity Testing
                        -Unroll the leads.
                        -Connect red clip to positive terminal of vehicle's battery.
                        -Connect black clip to negative terminal of vehicle's battery.
                        -Connect auxiliary ground lead to one side of tested wire along with probe tip connecting to the other side. When
                        continuity is present,the LED will light GREEN. If LED does not light up, no continuity present.
                        3.Testing Components Out of Vehicle's Electrical System
                        -Unroll the leads.
                        -Connect red clip to positive terminal of vehicle's battery.
                        -Connect black clip to negative terminal of vehicle's battery.
                        -Connect auxiliary ground lead to negative terminal of tested component.
                        -Press button to (-) side with LED lighting RED. Contact the probe tip to positive terminal of tested component to
                        active the component.If LED turns to GREEN with buzzer sounding, stop testing and check the component if defective
                        or not, or rating current of component is higher than that of this tester.

                        The black clip and auxiliary ground lead are connected directly through the unit. User can consider it as a long jumper
                        test lead by leave the red clip disconnected from the battery.
                        6.  Jumper Lead Operation
                        For some components of which neqative terminal is required to be well grounded for large current fowing, this tester
                        is a good tool to test their grounding.
                        -Unroll the leads.
                        -Connect red clip to positive terminal of vehicle's battery.
                        -Connect black clip to negative terminal of vehicle's battery.
                        -Press button to"-"side, the LED should light RED, and positive voltaqe is supplied. Then have the probe tip quickly contact
                        negative terminal of component as dose as possible, LED indicator turns to GREEN with buzzer sounding, which means it
                        is well grounded. If NOT, the LED remains RED without any buzzer.
                        7. Short Circuit Following and Locating

                        -Press button to "-" side, the LED should light RED, and positive voltage is supplied.
                        -Remove the blown fuse from the fuse box and begin trackinq from two terminals of the fuse socket.Use probe tip quickly
                        contact wire. If LED lights GREEN with buzzer, short circuit or overloading component appears in this side. Please note this
                        wire' s color or identification code. Follow the wire as far as you can alonc the wiring harness. Locate the color-coded wire in
                        the harness and expose it. Cut the wire. Follow the wire in the shorted direction and repeat this process until the short is located.
                        If there are components in the following wire, check the components individually if good or not.
                         
                        Note:
                        1. Do not use on AC voltage.
                        2. Don't use it if it is damaged.
                        3. Don't use this item when driving.
                        4. Before driving, please always make sure that the vehicle is safe and reliable.

                        5. The unit is not to be used with 110/220V house current, it is only use for DC 6~24V systems.
                        6. After you finishing checking vehicle, correctly restored all the connection-s which you disconnected.
                        7. Never touch any dangerous part of the vehicle with your hand for safety. Don't touch any live conductor with hand or skin.
                        8. Do not use the item around explosive gas, vapor, or dust. When the power switch is pressed (or rocked), battery current is
                        conducted directly to the tip which may cause sparks when contacting ground or certain circuits.
                        9. Always follow the instructions and procedures indicated in the vehicle's service manual before attempting to disconnect any
                        part or subsystem of the electrical circuit.
                        10. Some components of vehicle work on low voltage, they cannot withstand the voltage allied by the item. To avoid damage for
                        these components, don't use the item to apply voltage directly or indirectly.
