Measure Load Current Draws Without Stripping Power Cords And Isolate Receptacle Defects Instantly Using 10x Operational Frequency Splitting

The Klein Tools CL120KIT is a professional 3-piece electrical diagnostic testing set featuring the CL120 auto-ranging AC clamp multimeter, the 69409 10x line splitter, and the RT210 GFCI receptacle outlet analyzer. The primary hook-meter measures alternating current up to 400A AC and potential distributions up to 600V AC/DC across non-linear mechanical system branches. Combined with the included structural multiplier loop, this installation system permits safe real-time load diagnostics up to 15A without stripping power cord jackets, while the companion three-prong socket tester isolates missing grounds or reversed polarity lines inside structural boxes.

Best Used For:

  • Inline Cord Diagnostics: Interfacing the 10x multiplier attachment to capture small induction amp draws up to 15A on unstripped appliance connection lines.
  • Blower Motor Sweeps: Clamping the 1.61-inch spring jaw assembly over primary electrical supply paths to measure operational heating or cooling fan active consumption.
  • Receptacle Safety Audits: Inserting the multi-LED verification block into standard three-prong wall sockets to expose hidden branch grounding faults or neutral errors.

Key Performance & Safety Features

  • Triple-Instrument Testing Set: Bundles a 2000-count backlit digital clamp meter, a specialized 10x inline line splitter, and an advanced ground-fault plug analyzer.
  • Cord Preserving Splitter: Multiplier module splits active lines internally to enable inductive measuring methods on standard two-wire or three-wire peripheral leads.
  • Five-Point Circuit Auditing: Socket analyzer maps critical system connection bugs including open grounds, reversed polarities, open hots, open neutrals, and hot/ground shorts.
  • Simultaneous Interrupter Safety Audits: Analyzer face incorporates an isolated manual toggle trigger to verify ground-fault circuit interrupter hardware trip performance.
  • Padded Storage Enclosure: Includes a heavy-duty fabric zipper pouch with specialized interior divisions to protect individual diagnostic tools from field impact abrasion.
  • Industrial Protection Index: Dual-insulated meter framework assembly passes jobsite drop testing requirements on solid concrete from heights up to 6.6 feet.
