This compact meter delivers accurate checks for current and frequency in tight panels. The Extech 380947 True RMS AC/DC Mini Clamp Meter reaches cramped conductors while keeping readings stable and easy to read.

Precision in tight spaces

The small jaw slips around cables in narrow cabinets and trays with minimal effort. It helps technicians work quickly while avoiding the need to disconnect circuits during routine fault finding.

Stable results you can trust

It measures alternating and direct current with dependable linearity across its ranges. True RMS processing maintains accuracy when loads generate noise or distorted waveforms across typical installations.

Low-current sensitivity supports tracing parasitic draw on vehicles and small machines with confidence. Frequency capture assists with motor, drive, and generator checks during commissioning and maintenance without extra tools.

Included battery and manual mean you can start testing as soon as it arrives at the job. The tough, compact body rides easily in a pouch, so it is ready for plant, electrical, HVAC, telecom, and home tasks whenever you are.

Key features
  • Compact clamp body reaches crowded cabinets
  • Low-current sensitivity helps trace small draws
  • Measures alternating and direct current in one tool
  • Frequency capture supports motor diagnostics
  • Maintains accuracy on distorted waveforms
  • One-handed clamp action speeds quick checks
  • Clear resolution aids fault finding and logging
  • Lightweight build reduces fatigue during rounds
  • Suitable for plant, electrical, HVAC and telecom
  • Supplied ready to work with battery and manual
