• 1.8% basic accuracy
  • Up to 0.01A and 0.1V resolution
  • AC current to 400A
  • AC volts to 600V
  • DC volts to 600V (322 only)
  • Resistance measurement to 400Ω


The Fluke 321 and 322 clamp meters are designed to verify the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts. These small and rugged clamp meters are ideally suited for current measurements up to 400A in tight cable compartments. The Fluke 322 meter also offers DC voltage measurements and has a higher resolution for loads below 40 A.

Fluke clamp meters feature an inrush feature which measures motor starting current like a circuit breaker or overload unit sees it. One button lets you troubleshoot current surges that can cause nuisance tripping. Fluke's inrush feature gives you a synchronized reading of the current draw profile from motor start up.
