4.3 Setting Scaling Upper and Lower Limits (analog
input)
Ă• When an analog input (voltage input) is selected, scaling matched to the
control is possible.
Ă• Scaling is set in the scaling upper limit", scaling lower limit" and decĆ
imal point" parameters (initial setting level). These parameters cannot
be used when temperature input type is selected.
Ă• 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 lowerĆlimit
value of input. The decimal point" parameter specifies the number of
digits past the decimal point.
Ă• The following figure shows a scaling example of 0 to 5 mV input. After
scaling, the humidity can be directly read.

In this example, let's set the scaling upperĆ and lowerĆlimits so that inputs
0 to 50 mV are 10.0% to 95.0%.
(1) Press the key for at least three seconds to move from the operaĆ
tion level" to the initial setting level".
(2) Select scaling upper limit" by pressing .
(3) Press the or key to set the parameter to 950".
(4) Select scaling lower limit" by pressing .
(5) Press the or key to set the parameter to 100".
(6) Select the decimal point position by pressing .
(7) Press the or key to set the parameter to 1".
(8) To return to the operation level" press the key for at least one
second.
