Specification Assumptions
• Accuracy is given as ±(% of reading + counts of least significant digit) at 23 °C ± 5 °C, with relative humidity less than
80% RH.
• AC V and AC μA/mA/A specifications are AC coupled, true RMS and are valid from 5% of range to 100% of range.
• The crest factor may be up to 3.0 at full scale except for the 1000 V range where it is 1.5 at full scale.
• For non-sinusoidal waveforms, add (2% reading + 2% full scale) typical, for crest factors up to 3.
• After Z

voltage measurements, wait at least 20 minutes for thermal impact to cool before proceeding with any other
measurement.
