Electrical Power Testing

The Fluke 9040 Phase Rotation Indicator is a portable handheld instrument designed to detect the rotary field of three-phase systems. With three test leads, this rugged tester easily determines a clockwise or counterclockwise direction.

By simply twisting the test lead the user can change the exposed probe tip length from 19 mm to 4 mm (0.75 in to 0.16 in).
