Klein Tools CL460S 400A AC/DC Auto-Ranging Smart Digital Clamp Meter

The Klein Tools CL460S Smart Digital Clamp Meter is a True RMS (TRMS) electrical testing instrument engineered to measure AC/DC current up to 400A and AC/DC voltage up to 600V. Featuring CAT III 600V safety certification, auto-detection SMART mode technology, and a 1.25-inch clamp jaw opening, this 11.92 oz diagnostic meter automatically detects measurement parameters across voltage, current, resistance, and continuity to troubleshoot commercial electrical panels and HVAC control circuits safely.

Best Used For:

  • Commercial Panel Troubleshooting: Measuring 400A AC/DC current and 600V AC/DC voltage without manual dial switching using intelligent SMART mode auto-detection.
  • HVAC Equipment Servicing: Testing flame sensors, capacitance up to 4000µF, and system temperatures from -40°F to 1832°F using the included thermocouple probe.
  • Non-Contact Voltage Verification: Locating live electrical conductors inside conduit runs or junction boxes using integrated Non-Contact Voltage (NCVT) testing.

Key Performance & Safety Features

  • SMART Mode Auto-Detection: Automatically identifies and switches between voltage, current, resistance, and continuity measurements without manual dial adjustment.
  • TRMS Precision Auto-Ranging: Delivers true root mean square accuracy across linear and non-linear electrical loads for reliable jobsite diagnostics.
  • Reverse-Contrast Backlit Display: 4000-count illuminated LCD screen provides high-contrast parameter legibility in dark electrical rooms and direct sunlight.
  • Hands-Free Built-in Lead Holder: Molded storage slots hold test leads securely on the meter body for streamlined single-hand probing operations.
  • Jobsite Impact Protection: Rugged ABS housing withstands 6.5-foot (2-meter) drop impacts and features Class 2 double insulation with CE certification.
  • Comprehensive Multi-Function Suite: Measures DC microamps (400µA), resistance (40MΩ), frequency (10Hz–60kHz), diode test, duty cycle, min/max values, and data hold.
