Testo 770-1 True-RMS Clamp Meter - 400 A AC/DC, 600 V, Inrush

Overview

The Testo 770-1 is a True RMS clamp meter that measures 400 A AC/DC and 600 V AC/DC with automatic AC/DC detection for faster work with fewer steps. Its patented slide-out hook jaw isolates a single conductor in tightly packed cabinets, while inrush capture and True RMS give accurate readings on non-linear loads. Rated CAT IV 600 V / CAT III 1000 V, it is the essential everyday clamp meter for electricians.
