 To manually adjust the PID parameters
If the Autotuning (AT) function does not match the controlled object requirements, the optimum PID
values may not be calculated by Autotuning (AT). In that case, adjust the PID parameters manually.
• Change the Proportional band (P)
[Example: Change the Proportional band (P) to 20 °C]
1. Press and hold the key for 2 seconds or more at the PV/SV monitor screen to go to the
Parameter setting mode, and press the key to display the Proportional band [heat-side] screen.
2. Press the , , and keys to change from “0015” to “0020.” Press the key to store
the new value.
• Change the Integral time (I) and Derivative time (D)
The setting procedure applies when the Integral time and the Derivative time are also set.
• Return to the PV/SV monitor
To return the PV/SV monitor, press
and hold the key for 2 seconds or more.
After a new value is displayed on the display by using and keys, if no key
operation is performed within 1 minute without pressing key, this instrument returns
