> 24 hourThey make it look like your getting alot of cord but you only get enough to piss you off... other then the it does what its supposed to

> 24 hourPerfect for its intended use. Youd pay 3 times as much for the ones that give you a volt reading.

> 24 hourTo glance at color (positive negative), One must uncomfortably have to twist the probe so that you can get the approximately 30° viewing angle, almost perfectly, and this will not work in sunlight, or bright shop conditions unless you put your head right over it and exact which makes it versatility of this tester very clumsy. Also the probe is just a little bit too long, although it may be needed in certain conditions it has to be sharpened never mind I just want to get another one of a different brand and a more prominent display… This was a good start but a waste of money

VXSCAN EM285 Electric Circuit Tester is the best electrical tester for reducing diagnostic time in automotive electrical systems. Connect this item with an automotive battery. And then the end of the power tester will detect the positive or negative voltage through switch. You can make your own judgment by the different color test lights.
Applications:
1.Test for continuity
2.Test for polarity of a voltage
3.Check lamp
4.Check electric motor
5.Power supply function may be selected
6.Track and locate short circuits
7.Test for bad ground contacts

Operation instruction

|---|---|---|
Quick self-testHook-up: unroll the unit’s cable. Clamp the red clip to the positive terminal of the vehicle’s battery, clamp the black clip to the negative terminal of the vehicle’s battery. Press the front part(-) of the power switch, the LED indicator should light RED. Press the rear part (=), the LED indicator should light GREEN. The unit is now ready to use. If the LED indicator did not light, the cause may be that the clip connections are not good or the unit is damaged. |
Polarity testingContacting the probe’s tip to a positive(+) circuit will light the LED indicator RED. Contacting the probe’s to a negative(-) circuit will light the LED indicator GREEN. Contacting the probe’s tip to an open circuit will be indicated by that the LED indicator is off. |
Continuity testingBy 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 LED indicator will light GREEN. Note: Don not press the power switch |

Testing trailer lamps and connectionsConnect the unit to a good battery. Clip the clip of the auxiliary ground lead to the trailer ground Probe the contacts at the jack while pressing the power switch’s front part(-). This lets you check the function and orientation of the trailer lamps. |
Jumper lead featureThe black clip and the auxiliary ground lead are connected directly through the unit. By leaving the red clip disconnected from the vehicle’s battery, the unit can be used as a long jumper lead. Be careful to avoid short circuits and overloading when using this jumper function. In this configuration, the leads are not protected by the unit’s circuit breaker. |
Checking for bad ground contactsProbe the suspected ground wire or contact with the probe tip. Observe the green LED indicator. Press the power swithc"s front part(" - ")then release. If the LED indicator changed from GREEN to RED, this is not a true ground. If the unit sounds, this circuit is more than likely a direct ground. Keep in mind that high current components such as starter motors will also cause the unit to sound. |
