320 Series Clamp Meters
Big features, small package
The Fluke 321 and 322 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 400 A in tight cable
compartments.
Model 322 also offers DC voltage measurements and has a higher resolution for loads
below 40 A.
