Description Versatile meters for field service or bench repair. The Fluke 77 IV digital multimeter has the features needed to repair most electrical and electronic problems. This meter is simple to use and has significant improvements over Fluke’s original 70 Series with more measurement functions, conformance to the latest safety standards, and a much larger display that’s easier to view.
