The Fluke 170 series multimeter defines a new benchmark for general purpose multimeters. They set the standard with a combination of precision, features, ease-of-use, safety and reliability. All models offer true rms ac voltage and current readings, 6,000 count resolution, min/max/averaging recording, as well as frequency and capacitance ranges. Other features unique to the 170 series include an input smoothing mode to filter rapidly changing inputs.
