Feature(may vary by option.)

●【CIRCUIT TESTER WIDELY APPLICATION】Automotive Circuit Test Probe EM287 can be used to test continuity, test polarity of a voltage, check lamp, check electric motor, follow and locate short circuits, test for bad ground contacts and measure dc voltage from 2V to 24V etc.
●【HAS LONG TEST LEAD】Electrical System Analyzer has long test lead. The cable length is about 5m(16ft) which allows you test any electrical system easily.
●【OVERLOAD PROTECTION】Car Electrical Diagnostic Tool Overload Protection: When the current exceeds 8A, the unit will disconnect the current automatically.
●【EASY TO USE】Automotive Electrical Test Equipment, its easy to use. Battery by the vehicle battery directly. The illumination function enables automotive technician to test the electrical system in the darkness.
●【INSUFFINIENT LIGHT ENVIRONMENT】Automotive Wire Tracer takes the insufficient light environment in consider, the tool built in flashlight to indicate the DC voltage measurement.

OPERATION INSTRUCTION


1.Testing the Unit and the Connections Press the front part(“－’’)of the rock switch,the test indicator should light RED. Press the rear part (“＝’’),the test indicator should light GREEN. The unit is now ready for use. If the test indicator did not light,the cause may be that the clip connections are not good or the unit is damaged.	2. Using Illumination To turn on or off the illuminator,keep the clip of the auxiliary ground lead in contact with the TOUCH metal for about 0.5 second and then remove the clip from the TOUCH metal.	3.Measuring DC Voltage a.Set the selection switch to “VOLTAGE” position. b.Connect the probe to the more positive terminal of the circuit to be measured,and the clip of the auxiliary ground lead to the more negative terminal of the circuit. c.The voltage indicators will illuminate to indicate the voltage of the circuit.	4.Polarity Test Note:Set the selection switch to “TEST”position. Contacting the probe’s tip to a positive(+) circuit will light the test indicator RED.Contacting the probe’s tip to a negative(－)circuit will light the test indicator GREEN.Contacting the probe’s tip to an open circuit does not turn on the test indicator.

OPERATION INSTRUCTION


5.Continuity Test Note:1.Set the selection switch to “TEST”position. 2. Don’t press the rock switch, By using the probe tip together with the auxiliary ground lead, continuity can be tested on wires and components which are disconnected from the vehicle’s electrical system. When continuity is present, the test indicator will light GREEN.	6.Activating Components out of the Vehicle’s Electrical System Note:Set the selection switch to”TEST”position. By using the probe tip together with the auxiliary ground lead,components can be activated,thereby testing their function. Connect the auxiliary ground lead’s clip to the negative terminal of the component to be tested.Contact the probe to the positive terminal of the component, the test indicator should light GREEN indicating continuity through the component.	7. Testing Trailer Lamps and Connections 1)Set the selection switch to “TEST”position. 2)Connect the unit to a good battery. 3)Clip the clip of the auxiliary ground lead to the trailer ground. 4)Probe the contacts at the jack while pressing the rock switch’s front par((“－’’).This lets you check the operation and orientation of the trailer lamps.

OPERATION INSTRUCTION


8.Activating Electrical Components Note:Set the selection switch to”TEST”position. a.Activating components with the positive(+)voltage,Contact the probe tip to the positive terminal of the component,the test indicator should light GREEN.While keeping an eye on the green indicator,quickly press and release the rock switch’s front part(“－’’).If the green indicator changed instantly from GREEN to RED,you may proceed with further activation.If the green indicator went off at that instant,the uit has been overloaded. b.Activating electrical components with negative(－)voltage Contact the probe tip to the negative terminal of the component,the test indicator should light RED.	9.Jumper Lead Feature Note:Set the selection switch to”TEST” position. The black battery clip and the auxiliary ground lead are connected directly through the unit.By leaving the red battery clip disconnected from the vehicle’s battery,the unit can be used as a long jumper lead. Be careful to avoid short circuit and overloading when using this jumper function.In this configuration, the leads are not protected by the unit’s built-in circuit breaker.	10.Checking for Bad Ground Contacts Note:Set the selection switch to”TEST”position. Probe the suspected ground wire or contact with the probe tip.Observe the green test indicator. Press the rock switch’s front part(“－”)then release. If the test indicator changed from GREEN to RED,this is not a true ground. If the test indicator turned off when you pressed the rock switch’s front part(“－”)
