• An analog voltage input can be scaled matched to the control application.
• Scaling is set in the "scaling upper limit," "scaling lower limit," and "deci-
mal point" parameters. These parameters cannot be used when a tem-
perature input 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 dig-
its past the decimal point.
• The following figure shows a scaling example for a input of 0 to 50 mVDC
for humidity. After scaling, the humidity(%) can be directly read.

In this example, the scaling upper and lower limits are set so that inputs 0 to
50 mV are scaled to 10.0% to 95.0%.
