Overview The three models of the Fluke 170 Series True RMS digital multimeters are the benchmarks for general purpose multimeters. They set the standard with a combination of precision, features, ease-of-use, safety and reliability. Features True RMS voltage and current measurements 0.09% basic accuracy (177, 179) 6000 count resolution Digital display with analog bargraph and backlight (177, 179) Manual and automatic ranging Display Hold and Auto Hold Frequency and capacitance measurements Resistance, continuity and diode measurements Temperature measurements (179) Min-max-average recording Smoothing mode allows filtering of rapidly changing inputs Easy battery exchange without opening the case Closed case calibration through front panel Ergonomic case with integrated protective holster EN61010-1 CAT III 1000V / CAT IV 600V Measures twice as fast as other multimeters Safety conformance All inputs are protected to IEN61010-1 CAT IV 600V/CAT III 1000V.
