5.13 Averaging Inputs

The averaging function smooths the displays and outputs for input values with dramatic fluctuations, such
as spike noise.
Explanation of Functions
There are two types of averaging: "simple" and "moving." Select one type. The number of samples
("averaging times") can also be specified for the input values to be averaged.
Simple average is used when the display refresh period is to be lengthened. Moving average is used to
remove periodic noise superimposed on input signals. For example, with the K3HB-S, the relationship
between the data refresh periods for both simple and moving averages when the averaging times is set to
4 is shown below.
