3.4.3 CH[ ] Time/Count/Moving average/Time constant setting (Un\G1 to
Un\G8)
When the averaging processing (1H to 4H) is specified with Averaging processing
selection (Un\G24, Un\G25), time average, count average, moving average or time
constant for primary delay filter is set. (Refer to Section 3.2.1)
(1) Setting methods
(a) Set the following setting range in buffer memory.
* 1 Set the values in units of 320ms.
For the details of the setting values, refer to Section 3.2.1 (3) Averaging processing or Section
3.2.1 (4) Primary delay filter.
(b) Turn on Operating condition setting request (Y9) to activate the setting. (Refer to
