Introduction
This section contains information that will help you get more useful measurement data and better
instrument performance.
Optimizing either measurement accuracy or speed
You can use resolution, NPLC, autozero, and filter to optimize measurement accuracy and speed.
You can configure the following parameters to optimize for either measurement accuracy or
measurement speed.
Measurement resolution: Number of digits displayed
Integration time: Number of power line cycles (NPLC)
Autozero: Minimizing measurement drift
Filtering: A type of averaging
Changing the resolution automatically adjusts some of these parameters.
