With this tool, you can quickly diagnose problems with your circuits. First, it has a non-contact voltage detector. When just held near the wire or outlet it signals the presence of live circuit from 50 to 600V AC both visibly and audibly. Fully adjustable for surface to deep wall readings.
Second, you can also easily measure the exact voltage of AC or DC circuitry using its clever retractable probe in combination with its 30" long test lead. By combining one of the test probes in the body, this design uniquely allows you to manage the tester with two hands – a very big deal. Other functions include continuity testing, resistance measuring, and testing diodes. This tool should be your go-to for troubleshooting anything. And it comes with an alternate test lead for the accessory alligator clip. We think very highly of this tester.
