Detailed Specifications

Accuracy:
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 ] ). Accuracy
specification assumes ambient temperature stable at ±1 C. For ambient temperature changes of ±5 C, rated accuracy
applies after 2 hours. To obtain full accuracy in DC mV, Temperature, Ohms and Lo (50) Ohms, let the meter stabilize 20
minutes after using LoZ.
True-rms:
AC mV, AC V, AC μA, AC mA, and AC A specifications are ac-coupled, true rms, and are specified from 2 % of range to
100 % of range, except 10 A range is specified from 10 % to 100 % of range.
Crest Factor:
Accuracy is specified with AC crest factor
range, where it is 1.5 at full scale, increasing linearly to 3.0 at half-scale and 500 mV and 5000 A, where it is 3.0 at 80
% of full scale, increasing linearly to 5.0 at half-scale. For non-sinusoidal waveforms add ±(0.3 % of range and 0.1 % of
reading).
AC Floor:
When the input leads are shorted together in the ac functions, the Meter may display a residual reading up to 200 counts.
A 200 count residual reading will cause only a 20 count change for readings at 2 % of range. Using REL to offset this
reading may produce a much larger constant error in later measurements.
