Previous average value comparison makes the measurement value the difference between the present
input value and the average of all previous input values.
(Vn indicates the input value and Cn indicates the comparative set value used for the next input.)
* Previous average value comparison is performed on confirmed measurement values.
• When the timing hold is set to Normal, the comparison is performed every time.
•
When the timing hold is set to a setting other than Normal, the comparison is performed on held values.
Previous average value comparison is set using the following
parameter.
