Accuracy
See the Specifications section for operating conditions and temperature coefficient.
Accuracy is specified as follows:

F), 0% to 75% relative humidity.
True RMS readings: Accuracies are specified from 5% to 100% of the range unless otherwise
specified. Frequency must be within the specified bandwidth for non-sinusoidal waveforms.
Crest factors are as follows:
• Crest factor < 3:1 at full scale
• Crest factor < 6:1 at half scale
