8.2.10 Damping Constant

The damping constant is used to moderate output fluctuations. (The larger the damping constant, the more
the output is averaged. But the response to an input change will be slower.) The damping constant can be
set as follows:
The damping constant is set for 0.0 sec, 0.5 sec and 1 to 60 sec (in increments of 1 second)
Note: 0.0 sec setting will work as equal to 0.1 sec damping constant.
Set 1 sec or more for normal operation.
If you set a value exceeding 60s, it is forcibly changed to 60s before data is written.
Proceed as follows to check or change the damping constant.
Shown below is an example of changing the damping constant from 2.0s to 10s.
