Detailed Accuracy Specifications

Accuracy is specified for a period of one year after calibration, at 18 ° C to 28 ° C (64 ° F to 82 ° F), with relative humidity to 90 %. Accuracy specifications are given as:

±( [ % of reading ] + [ number of least significant digits ] )

AC mV, AC V, AC µA, AC mA, and AC A specifications are ac coupled, true rms and are valid from 5 % of range to 100 % of range. AC crest factor can be up to 3.0 at full-scale, 6.0 at half-scale except the 3000 mV and 1000 V ranges where it is 1.5 at full scale, 3.0 at half-scale.

1.For the 5,000 count mode, divide the number of least significant digits (counts) by 10.

2.A residual reading of 8 to 180 digits with leads shorted, will not affect stated accuracy above 5 % of range.
