The 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.Warnings Do NOT use with current loads greater than 15A (which would be displayed as greater than 150A on a clamp meter using the Line Splitter 10x). Always wear approved eye protection. Do not use if Line Splitter 10x appears damaged in any way; do not use if wet, intended for indoor use only. Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use. Features Provides 10X measurement mode Measures up to 15A with +/- 3% Accuracy Allows the measuring of current draw up to 15A without splitting the load's power cord For use with all Klein clamp meters For North American-style outlets only Can be used to perform voltage checks with standard multimeter probes Overall Length: 4.67 in (11.9 cm) Overall Height: 4.67 in (11.9 cm) Overall Width: 2.28 in (5.8 cm) Weight: 0.244 lbs (3.9 oz) Drop Protection: 3.3 ft (1 m) Current Capacity: 15A Voltage Rating: 120V Accuracy: 3% Measurement Multiplier: 10x Country of Origin: China Instructions69409_instructions.pdfDownloadsVideo DownloadSpec Sheet
