• To switch the temperature unit from _C" to_F" when input is temper
ature, switch the _C/_F selection" parameter (setup mode) from  "
to  ".
• When input is temperature input, the upper and lower limit values of the
sensor can be shifted linearly. For example, if both the upper and lower
limit values are shifted by 1.2_C, the process value (before shift) is re
garded as 201.2_C after shift when input is 200_C before shift.
• To set input shift, set shift values in the input shift upper limit" and in
put shift lower limit" parameters (level 2 mode).

• When the analog input (the voltage input and current input) is selected,
scaling matched to the control is required.
• The scaling upper limit", scaling lower limit" and decimal point" pa
rameters (setup mode) are used for scaling. These parameters cannot be
used when the temperature input type is selected.
• The scaling upper limit" parameter sets the physical quantity to be ex
pressed 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 sets the number of digits
past the decimal point.
• The following figure shows a scaling example of 4 to 20 mA input. After
scaling, the humidity can be directly read. In this case, the decimal
point" parameter is set to 1".
