Determine at a glance whether the circuit is positive, negative without having to reconnect the clips from one battery post to the other. 2. Use the built in auxiliary ground lead to test for continuity. 3. Press the power switch to drive a positive or negative battery current to the probe tip to test the functionality of electrical components without using jumper cables. 4. Immediately test for incorrect ground contact without a voltage drop test.

1. Determine at a glance whether the circuit is positive, negative without having to reconnect the clips from one battery post to the other.
2. Use the built-in auxiliary ground lead to test for continuity.
3. Press the power switch to drive a positive or negative battery current to the probe tip to test the functionality of electrical components without using jumper cables.
4. Immediately test for incorrect ground contact without a voltage drop test. The tool is also short-circuit protected; your internal circuit breaker will trip if overloaded.
5. Trace and locate the short without losing the fuse. The tools 20-foot cable allows you to test along the entire length of the vehicle without the constant search for a suitable vehicle ground point.
6. Perform various types of services including power injection, metering, grounding tests, polarity checks, continuity tests and component activation.
7. Easy-to-read multimeter allows you to easily read voltage, current and resistance
8. Integrated flashlight lets you work in the dark
