You need the Test Meter Kit featuring the Fluke T5 electrical tester when trying to find a safe metallic contact point. Check voltage, continuity, and current with one compact tool by selecting volts, ohms, or currents, and the tester does the rest. Its tough test leads stow neatly in the back of the tester, making it easy to tote the T5 in your tool pouch. The test leads accept optional accessories such as clips and specialty probes. And with the pocket-sized voltage detector is the next-generation voltage tester from Fluke. When the tip glows red, and the unit beeps, you know there's voltage present. So be prepared on the jobsite with the Test Meter Kit.
