Auto Tuning
In Auto Tuning the characteristics (PID parameters) of the controller are matched to the
characteristics of the product load in order to obtain good control.
Good control means:

Stable control of the set point

No overshoot or undershoot

Quick response to deviations from the set point

Removal of fluctuations
The 3216 controller uses a one-shot tuner which automatically sets the initial values of
the parameters listed in Table 2 “Parameter Description and Accessibility in 3216c” and
Table 3 “Parameter Description and Accessibility in 3216p”.
Thermo Fisher recommends that you tune the furnace to your specific application to
obtain the best results.
Steps to Auto Tune the Controller
1. Load the chamber with materials that have the same mass and thermal
characteristics as a typical product load.
2. Set the temperature as per requirement; refer to section “Single Set Point Operation”
on setting SP1 or SP2.
3. Press SCROLL button to scroll through the list of parameters until A.TUNE is
displayed.
NOTE Do not use nonE & PErc, they are used to measure other applications types
other than temperature.
