Adjustment Level Section 7-4
Function The entire input range is shifted by a fixed rate (one-point shift). If the input
shift value is set to
−1.0°C, the SP is controlled to a value obtained by
subtracting 1.0
°C from the actual temperature.

Lower Limit Temperature Input Shift Value (insl)
Condition: Refer to the following table for details.
These parameters allow the input range to be shifted both at the upper and
lower limits (two-point shift) (as opposed to the “temperature input shift”
parameter, where the entire input range is shifted by a fixed rate (one-point
shift)). A two-point shift enables more accurate offset of the input range
compared with a one-point shift when the input shift values at the upper and
lower limits differ.
Conditions of Use
Note Two-point shift can be used with platinum-resistance thermometers and
thermocouples for upgraded pulse output models and analog output models only.
Function This parameter sets input shift values for each of the upper and lower limits
(two-point shift) of the input range.
