Since 1857.Klein Tools 69409 Line Splitter 10xThe Klein Tools 69409 Line Splitter separates hot from neutral and ground wires on standard 120-Volt outlets so that current measurements can be made with a current clamp. Without the Line Splitter, the current clamp measures the load current going in both directions, effectively cancelling the measurement. The Line Splitter has a standard measurement section and ten-times multiplier section for use with less accurate or higher ranged clamp meters. It was designed for use with Klein Tools clamp meters but will also function with many other manufacturers' clamp meters. ## Features - Product 1: CLEAR COLOR LCD DISPLAY: Circuit Analyzer with large color LCD provides easy-to-understand results for wiring faults, AFCI, GFCI, voltage drops, and device trip time - Product 1: COMPREHENSIVE WIRING FAULT DETECTION: Detect and identify common wiring faults in standard, AFCI, and GFCI electrical outlets, ensuring thorough evaluation - Product 1: DUAL WIRING FAULT DETECTION: Capable of detecting dual wiring faults, including open neutral and open ground, enhancing safety measures - Product 1: AFCI AND GFCI DEVICE INSPECTION: Inspect AFCI and GFCI devices, measuring trip time and trip current for accurate functionality assessment - Product 2: Allows the measuring of current draw up to 15A without splitting the load's power cord - Product 2: For use with all Klein clamp meters - Product 2: Can be used to perform voltage checks with standard multimeter probes - Product 2: Provides 10X measurement mode ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CX5H34MG | | Brand | Klein Tools | | Color | Orange | | Date First Available | March 5, 2024 | | Item model number | c9253482-7672-4ee7-8801-07a349fd57bd | | Manufacturer | Klein Tools | | Min.
