Setting Scaling Upper and Lower Limits for Analog Inputs
4-3-1
Analog Input
• When an analog input is selected, scaling can be performed as needed
by the control application.
• Scaling is set in the “scaling upper limit,” “scaling lower limit,” and “deci-
mal point” parameters (initial setting level). These parameters cannot be
used when a temperature 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 below the decimal point.
• The following figure shows a scaling example for a 4 to 20 mV input.
After scaling, the humidity can be directly read. Here, one place below the
decimal point is set.
Operating Procedure
In this example scaling is set to display 4 to 20 mA as 10.0% to 95.0%.

Initial Setting Level
1.
Press the
O
key for three seconds to move from the operation level to
the initial setting level.
2.
Select “scaling upper limit” by pressing the
M
key.
3.
Use the
U
and
D
keys to set the parameter to 950.
4.
Select the “scaling lower limit” parameter by pressing the
M
key.
5.
Press the
U
and
D
keys to set 100.
6.
Select the “decimal point” parameter by pressing the
M
key.
