The psiber CT12 CableTracker's incredible 190mW power output helps to quickly and accurately solve the most difficult cabling installation and maintenance jobs. The psiber CT12 CableTracker “ON” transmits the tone signals continuously until the operator turns the unit off, while “AUTO” transmits the tone signals for approximately 12 minutes and then shuts down to conserve battery life. The psiber CT12 CableTracker 12 comes with an RJ-45 patch cable for connection to modular jacks and an RJ-45 to alligator clips adapter for toning punch down blocks, bare wires or non terminated cables.
