Shifting Input Values Section 4-1
3. After setting the input shift values, check the Controller readout (A) and the
control target temperature (B). If they are approximately the same, this
completes setting the input shift.
Method for a 2-point
Shift
Use a 2-point input shift if you want to increase the accuracy of the readout
values across the range of the Sensor.
1,2,3... 1. Shift the Controller readout at two points, near room temperature and near
the value at which the temperature of the control target is to be controlled.
For this reason, check the thermometer temperature (B) and Controller
readout (A) with the thermometer temperature near room temperature and
near the set point.
2.
• Y1 is the Controller readout at room temperature before shifting and
X1 is the Controller readout at room temperature after shifting.
• Y2 is the Controller readout at the set temperature before shifting and
X2 is the Controller readout at the set temperature after shifting.
• Set the upper-limit temperature input shift and the lower-limit temper-
ature input shift using the following formulas based on the tempera-
tures before shifting (Y1 and Y2), the temperatures after shifting (X1
and X2), the set temperature upper limit (YH), and the set temperature
lower limit (YL). The shift is illustrated in Figure 3.
