The Fluke i3000s-24 Flex is an ac current clamp utilizing the Rogowski principle. It can be used to measure currents from 3 to 3000 AC when used in conjunction with oscilloscopes, recorders or data loggers. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas. The i3000s Flexprovide a low voltage 3 V AC output that is proportional to the current being measured. The Probes provide full-scale direct readings for 30 A, 300 A, and 3000 A.
