Specification Sheet

3 Fluke Corporation Fluke 170 Series True-rms Digital Multimeters
 All AC voltage and AC current ranges are specified from 5 % of range to 100 % of range.
 Crest factor of ≤ 3 at full scale up to 500 V, decreasing linearly to crest factor ≤ 1.5 at 1000 V.
 For non-sinusoidal waveforms, add -(2 % reading + 2 % full scale) typical, for crest factors up to 3.
 In the 9999 F range for measurements to 1000 F, the measurement accuracy is 1.2 % + 2 for all models.
 Amps input burden voltage (typical): 400 mA input 2 mV/mA, 10 A input 37 mV/A.
 400.0 mA accuracy specified up to 600 mA overload.
 > 10A unspecified.

For DC functions, accuracy is the specified accuracy of the measurement function ± 12 counts for changes longer
than 350 ms in duration.
For AC functions, accuracy is the specified accuracy of the measurement function ± 40 counts for changes longer
than 900 ms in duration
Specifications
Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 %
to 90 %. Accuracy specifications take the form of: ± ( [ % of Reading ] + [ Counts ] )
