SPCtelco JackTest+ Single Ended RJ45 / RJ11 Tester

The SPCtelco™ JackTEST+ RJ45 / RJ11 Identifier is a simple, single-ended go/no-go tester designed to aid installers and MIS personnel in identifying both LAN and phone jacks. The LAN plug is designed to detect the absence of a given pair's closed conductance loop inside the LAN jack under test. This test also has the ability to diagnose an analog/digital telephone line's jack. The phone plug detects the correct tip/ring polarity as normal, reversed or not connected.

The JackTEST+ comes with the CR2032 type battery.
