Fluke 83V and 87V Digital Multimeters Detailed Specifications For all detailed specifications: Accuracy is given as ( % of reading + number of least significant digits ) at 18 C to 28 C, with relative humidity up to 90 %, for a period of one year after calibration. 1 For Model 87 in the 4 2-digit mode, multiply the number of least significant digits (counts) by 10. AC conversions are ac-coupled and valid from 3 % to 100 % of range. Model 87 is true-rms responding. AC crest factor can be up to 3 at full scale, 6 at half scale. For non-sinusoidal wave forms add -(2 % Rdg + 2 % full scale) typical, for a crest factor up to 3.

When the input leads are shorted together in the ac functions, the meter may display a residual reading between 1 and 30 counts. A 30-count residual reading will cause only a 2-digit change for readings over 3 % of range. Using REL to offset this reading may produce a much larger constant error in later measurements. 3 Frequency range: 1 kHz to 2.5 kHz. 4 A residual reading of up to 13 digits with leads shorted, will not affect stated accuracy above 3 % of range. 5 Specification increases from -1 % at 200 Hz to -6 % at 440 Hz when filter is in use.

When the input leads are shorted together in the ac functions, the Meter may display a residual reading between 1 and 30 counts. A 30 count residual reading will cause only a 2 digit change for readings over 3 % of range. Using REL to offset this reading may produce a much larger constant error in later measurements. 4 10 A continuous up to 35 C < 20 minutes on, 5 minutes off at 35 C to 55 C. 20 A for 30 seconds maximum > 10 A unspecified. 5 Below a reading of 200 counts, add 10 counts. 6 400 mA continuous 600 mA for 18 hours maximum.
