Product Overview
The Klein Tools Tone Generator is a professional-grade analog tool engineered for tracing and testing open-ended, non-active wiring in telecommunications and data systems. Constructed from durable plastic and metal with a brushed finish, this rectangular-shaped device measures 2.5 x 1 x 4.25 inches and weighs 7.4 ounces, making it compact and portable. It operates as an ohmmeter with a minimum voltage of 6 volts and is powered by four included AAA batteries, providing up to 120 hours of average battery life. Key components include the Tone-PRO tone generator, Angled Bed of Nails (ABN) Teleco clips for secure wire connections, and an RJ11 plug for telephone or RJ45 data jacks, allowing individual conductor or wire pair toning. The device tests for continuity and polarity, with results displayed on clearly labeled LEDs, and features an auto power-off function and low battery indicator to enhance efficiency and reliability.
