Fluke 77 IV Data Sheet

Fluke 77IV

N10140

Digital Multimeter

Versatile meters for field service or bench repair

The NEW 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.

It measures:

Wide 1000 V measurement range

•

Average responding ac measurements

•

0.3 % accuracy

•

20 A for 30 seconds

•

Frequency and capacitance

•

Resistance and continuity

•
