Optimizing measurement accuracy
The configurations listed below assume that the multimeter after an ICL
command reset().
Enclosed are two charts that represent RMS Noise versus Aperture Time (or
NPLC) and Reading Rate versus Aperture Time (or NPLC). Refer to these
charts when selecting best accuracy at a given reading rate. Generally,
increasing the Aperture time reduces the RMS noise. For Aperture times
>100msec or 5PLC, thermal offsets can increase the RMS noise.
