■ Input shift
• Input shift is accomplished by 2-point correction.
• In the event that there is a large difference between the temperature
at the sensor position and the temperature at a location where a
temperature reading is required, with the result being that satis-
factory control is not possible, the temperature difference can be set
as an input shift value.
● 2-point correction
• Straight-line correction is accomplished by setting the value required
to correct "Input value for input shift 1" in "Input shift 1", and the
value required to correct "Input value for input shift 2" in "Input shift
2". Different correction values may be required for "Input shift 1" and
"Input shift 2", and thus the slope of the line between the two points
may differ before and after correction.
• Input shift is set for each channel. The input shift settings for inputs 1
to 4 of a multi-point input type correspond to channels 1 to 4. First
select a channel with the key and then set the corresponding
input shift values.
