When an analog input (voltage input) is selected, scaling matched to the
control is possible.
Scaling is set in the scaling upper limit", scaling lower limit" and dec
imal point" parameters (initial setting level). These parameters cannot
be used when temperature input type is selected.
The scaling upper limit" parameter sets the physical quantity to be
expressed by the upper limit value of input, and the scaling lower limit"
parameter sets the physical quantity to be expressed by the lower limit
value of input. The decimal point" parameter specifies the number of
digits past the decimal point.
The following figure shows a scaling example of 0 to 5 mV input. After
scaling, the humidity can be directly read.
