Setting Input Specifications
Section 4-1
This parameter can be set only when operation is stopped.
Always set the Scaling Upper Limit > Scaling Lower Limit.
If the Scaling Lower Limit > Scaling Upper Limit, the larger value will function
as the Scaling Upper Limit.

Setting Example
In this example, scaling is set to display 0 to 5 V as 10.0% to 95.0%.
Scaling Upper Limit = 950
Scaling Lower Limit = 100
Decimal Point Position = 1
4-1-4 Input Filter
Sets the time constant of the digital input filter.
