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.
For Model 87 in the 4 ½-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.

Below 10 % of range, add 12 counts.
The Meter is a true rms responding meter. 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.
Frequency range: 1 kHz to 2.5 kHz.
A residual reading of up to 13 digits with leads shorted, will not affect stated accuracy above 3 % of range.
Specification increases from -1% at 200 Hz to -6% at 440 Hz when filter is in use.
