Shifting Input Values Section 4-1
4-1 Shifting Input Values
4-1-1 Shifting Inputs
The input shift matched to the sensor currently selected in the Input Type
parameter is displayed.
• A 2-point shift is applied for infrared temperature sensors. A 2-point shift
can also be used if the Input Shift Type parameter (advanced function set-
ting level) is set to INS2 for a thermocouple or platinum resistance ther-
mometer.
• There is no shift for analog inputs. Use scaling for fine adjustments.
One-point shift
• With a 1-point shift, the value set for the Temperature Input Shift parame-
ter (adjustment level) is applied to each point in the entire temperature
input range. For example, if the input shift value is set to 1.2
°C, the pro-
cess value is treated as 201.2
°C after the input shift is applied when the
measured process value is 200
°C.
Operating Procedure In this example, the input from a K sensor is shifted by 1
°C using a 1-point
input shift.
