Accuracy
Refer to "Specifications" for operating conditions and temperature
coefficient.
Accuracy is specified as follows: ± (a percentage of the reading + a fixed
amount) at 23 °C ± 5 °C (73.4 °F ± 9 °F), 0% to 75% relative humidity.
True RMS readings: DM-300, DM-330, and DM-350 AC accuracies are
specified from 5% (10% for 600.0 mV range) 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 < 2:1 at full scale
• Crest factor < 4:1 at half scale
