Autotune the Temperature Controller
The M501-TRS controller includes an auto tune feature which allows the controller to
find and set optimum values for various process control parameters so that the controller
can establish and maintain the converter oven at the temperature set value in the most
stable and efficient manner.
NOTE
Before initiating the autotune feature make sure that the converter temperature oven
has reached a stable, constant temperature.
