(Varies with the setting of the decimal point position.
However, even if "3: Three decimal places" is set, the maximum settable decimal places
are 2.)
Factory set value:
[Input scale high]
RTD input: Maximum value of the selected input range
Voltage (V) input: 100.00
[Input scale low]
RTD input: Minimum value of the selected input range
Voltage (V) input: 0.00
Related parameters:
Input type (P. 9-45), Decimal point position (P. 9-46)
When a Voltage (V) input type is selected, the Input scale high can be set lower than the Input
scale low. (Input scale high < Input scale low)
