Tests, Tones, Troubleshoots, and Generates Reports
The Klein Tools Scout® Pro Max tests and troubleshoots RJ11, RJ12, RJ45, and F-connector terminated cables and provides analog and digital tone generation for cable tracing. It measures cable lengths (via TDR) and detects distance to faults. Generate reports to show custom test history. Tests shielded and unshielded cables. Trace up to 20 locations at a time with included remotes. Perform hub blink testing, measure active and passive Power over Ethernet (PoE). Test POTS (Plain Old Telephone Service), and detect active network capabilities.
