setting is different from when there is no mean processing, as shown in the
following diagram.
2.
Specify “no mean value processing” to follow conversion of a rapid change
in input signals.
3.
If the averaging function is used, the delay in the conversion data in com-
parison to changes in the input signals will be as shown below.
