Description
Overview
The Testo 770-1 is a True-RMS clamp meter that measures up to 400 A AC/DC and 600 V AC/DC. It detects AC or DC automatically, so there are fewer steps before each reading. Its patented slide-out hook jaw isolates a single conductor in tightly packed cabinets. Inrush capture and True-RMS measurement keep readings accurate on non-linear loads. With a CAT IV 600 V / CAT III 1000 V rating, it is a dependable everyday clamp meter for electricians.
