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.
• 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.

In this example, the input from a K sensor is shifted by 1 C using a 1-point
input shift.
Operation 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.
4. To return to the operation level, press the O key. The process value is
1 C larger than before the shift was applied.
