FLUKE Networks Pocket Toner NX2DLX Kit-Main, Toner Adap

The Pocket Toner tools are pocket-sized, durable test devices that allow users to quickly and easily test voice, data, video cables for open and short circuits, continuity, AC/DC voltage* and dial tone*.
Pocket Toner NX2 offers all the features of the NX1 plus more. The PTNX2 tests VDV cables for continuity, AC and DC voltage (low voltage protection and verification up to 52 volts), opens, shorts, 50-75 O termination, and polarity with the optional Dial Tone Detective adapter. The Pocket Toner NX2 easily confirms if there is AC or DC voltage, an open circuit on the line, if a short exists or if continuity is achieved. Pocket Toner NX2's key feature is the ability to know if the cable being tested is connected to any device with a voltage output of up to 52 volts.
Dial Tone Detective adapter
The Dial Tone Detective, is a low-cost, must have adapter that determines the presence of a dial tone. The bi-colored LED turns green indicating a dial tone - attach the adapter to one of the tone sections on any PTNX device to emit a sound at the same time. If the adapter turns red, there is a reversed pair on the jack under test.
