4.7 MATH
Simple math features are included for convenience and aid in setting up experiments. Readings can be
filtered to quiet effects of a noisy environment. Max and Min readings can be captured. A linear
equation can be applied to input data to correct system errors or improve performance of the analog
outputs. Math features can be performed on all eight sensor inputs. Each input must be configured
seperately.
4.7.1 Max/Min
The Max/Min feature simply captures and stores the highest (Max) and lowest (Min) reading taken
since the last reset. The feature will only capture from one reading source so it is important to select a
source. Max and min can be manually reset as described below. They are also reset when the
instrument is turned off or parameters related to the input are changed.
To select a source for Max/Min, press
Math

Press
