Fluke 355 AC/DC Clamp Meter
Introduction:
The Fluke 353 and 355 are hand-held battery-operated Clamp Meters (the Meter). Both Meters measure ac, dc true rms, inrush current and frequency; The 355 also measures ac, dc, true rms voltage, and resistance.
The Meter ships with:
- TL224 Test leads (355 only)
- AC285 Clips (355 only)
- TP74 Test Probes (355 only)
- Soft carrying case
- 6 AA/LR6 Batteries, installed
- 353/355 Users Manual (7 languages)
