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.
The Fluke 321 and 322 clamp meters are compact, rugged devices intended to verify load current, AC voltage, and continuity of circuits, switches, fuses and contacts. They are suited for current measurements up to 400 A in tight cable compartments, with the 322 model also offering DC voltage measurement and higher resolution for low‑current loads.
