The Gale PTNX2 is for the technician that works primarily with coaxial cable that wants a powerful but super-compact tool to fit in his or her pocket. In addition to testing for continuity and short circuits PTNX2 is packed with advanced features like indication of AC or DC voltage, 50-75 ohm terminators and auto shut-off to conserve battery life. The Gale PT-NX2 instantly displays all test results on an easy to read 8-segment LED display as well as giving audible feedback at both ends of the test cable. Like all Pocket Toner NX test tools, the PT:NX2 is now 100% low voltage protected so connecting it to live low voltage systems will not damage the tool.
