1. In the configuration shown in Figure 1, bring the set point to near the value
at which the temperature of the control target is to be controlled. Assume
that the control target temperature (C) and the thermocouple temperature
(B) are the same.
2. Check the control target temperature (B) and the Controller readout (A).
Subtract the Controller readout temperature (A) from the control target
temperature (B), and set insl and insh to the result as the input shift val-
ue. The shift is illustrated in Figure 2.
3. After setting the input shift values, check the Controller readout (A) and the
control target temperature (B). If they are almost the same, this completes
shifting the temperature input.
