Klein Tools CL900 Digital Clamp Meter

The Klein Tools CL900 digital clamp meter provides rugged auto-ranging TRMS diagnostics, measuring up to 2000A AC/DC current and 1000V AC/DC voltage for high-capacity industrial systems. Engineered for electrical technicians, it features a Low Impedance (LoZ) mode to eliminate ghost voltages and an Inrush Current capture mode for accurate motor startup analysis. Built with a CAT IV 600V safety rating and an integrated non-contact voltage tester, it ensures precise circuit verification across demanding jobsite environments.

Best Used For:

  • Industrial Motor Diagnostics: Capturing electrical startup surges and running current limits on heavy commercial machinery.
  • Electrical Panel Troubleshooting: Measuring high-amperage feeds and verifying line voltages up to 1000V safely.
  • Ghost Voltage Elimination: Filtering out induced phantom voltages in complex wiring bundles using LoZ mode.

Key Performance & Safety Features

  • 2000A AC/DC Clamp Measurement: Handles high-current diagnostics with ease.
  • 1000V AC/DC Voltage Range: Suitable for large-scale electrical systems.
  • Auto-Ranging TRMS Technology: Ensures accurate readings across variable loads.
  • LoZ Mode: Identifies and eliminates ghost voltages for safer testing.
  • Inrush Current Mode: Captures startup surge for motors and HVAC systems.
  • NCVT Integration: Built-in non-contact voltage detection for quick safety checks.
