Fluke 77IV
Digital Multimeter
It measures:
•
Wide 1000 V measurement range
•
Average responding ac measurements
•
0.3 % accuracy
•
20 A for 30 seconds
•

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 func-
tions, conformance to the latest safety standards,
and a much larger display that’s easier to view.
General specifications
Accuracy is specified for 1 year after calibration, at operating tempera-
tures of 18 °C to 28 °C, with relative humidity at 0 % to 90 %. Accuracy
specifications take the form of ±([ % of Reading ] + [ Counts ]).
