The temperature controllers used in the GC-Pro TCD are three-term

controllers with proportional (Kp), Integral (KI), and derivative (Kd)
settings. Together, these parameters determine the overall control and
response of the instrument.

Optimum values for Kp, KI, and Kd have been determined at the

factory and set for your instrument. The PID Settings menu from the
Temperature main menu will display the current values for each of the
three heaters and allow the user to modify the setting.

To access the parameters, press PID Settings from the Temperature

screen.

Pressing PID Settings will bring up the following screen that

displays the current settings for each of the three temperature
controllers.
