Klein Tools CL810 600A AC/DC True RMS Auto-Ranging Digital Clamp Meter with LoZ Mode

The Klein Tools CL810 Pro Digital Clamp Meter measures AC/DC current up to 600A and voltage up to 1000V for diagnosing complex industrial distribution panels, motor circuits, and commercial HVAC systems. Featuring True RMS auto-ranging technology, low impedance LoZ mode to eliminate false ghost voltages, and inrush current capture for compressor start-up loads, this diagnostic instrument delivers precision electrical testing. Engineered with an illuminated selector dial, non-contact voltage sensor in the clamp jaw, and a transflective reverse-contrast LCD, this drop-tested meter equips electricians and service technicians with clear visibility and reliable data across bright sunlight or dark electrical enclosures.

Best Used For:

  • Commercial HVAC & Motor Troubleshooting: Capturing motor inrush currents, flame sensor DC microamps, and temperature variations from -40°F to 1832°F.
  • Distribution Panel Diagnostics: Clamping conductors up to 1.4 inches in diameter to measure 600A AC/DC line currents in commercial power feeds.
  • Stray Voltage Identification: Engaging LoZ low input impedance mode to drain and eliminate capacitive ghost voltages on adjacent de-energized wiring.

Key Performance & Safety Features

  • True RMS Auto-Ranging Measurement: Delivers precise readings on linear and non-linear electrical loads across 1000V AC/DC and 600A AC/DC.
  • Low Impedance (LoZ) Mode: Identifies and eliminates ghost or stray voltages induced by parallel live conductors for dependable fault tracing.
  • Integrated Jaw NCVT Sensor: Detects live AC voltage without physical contact and emits escalating audio and visual alert signals.
  • Transflective Reverse-Contrast Display: 6000-count digital LCD screen remains readable under direct jobsite sunlight and dim electrical vault lighting.
  • CAT IV 600V & CAT III 1000V Safety Ratings: Built with 6.6-foot drop protection and IP40 dust resistance for high-energy commercial environments.
