Specifications

Accuracy

Accuracy is given for a period of one year after calibration, at 18 °C to 28 °C, with
relative humidity up to 90 % as:
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 5 % to 100 % of range.
Models 85 and 87 are 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 % reading + 2 % full scale) typical,
for a crest factor up to 3.
