The clamp can measure up to 1500VDC, 1000VAC, and up to 999.9 A DC or AC through the clamp jaw. The provided flexible current probe extended AC current measurements up to 2500A.

This clamp offers a thin jaw, enabling access to cables in crowded combiner boxes. It is IP54 rated, excellent outdoor use on solar arrays and wind power systems. The DC power measurement shows readings in kVA. An audio polarity indicator assists to prevent accidental miswires, and the visual continuity provide a bright green light in the display, excellent for dark and noisy environments.
