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
setting level) is set to INS2 for a thermocouple or platinum resistance
thermometer.
• 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.

Adjustment Level 1. Press the
O
key to move from the operation level to the adjustment level.
2. Select the “temperature input shift” parameter by pressing the
M
key.
3. Press the
U
or
D
key to set 1.0.
Operation Level 4. To return to the operation level, press the
O
key. The process value is
1
°
C larger than before the shift was applied.
