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 tool's 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
