19.1 PID Parameters and Tuning -- General
It is far beyond the scope of these instructions to explain all the finer points of PID
(Proportional, Integral, and Derivative) temperature control and tuning. Where necessary,
these instructions will provide some explanation of concepts that are different from standard
PID control.
The default PID values shown should suffice for most users. However, further tuning of the
PID parameters may be necessary for any given machine in order to obtain optimum
performance for any particular set of test conditions/requirements. The user should consult
a good engineering controls text or web site to become familiar with the concept of PID
parameters and tuning before making adjustments. Some helpful resources are shown
below:

19.2 PID temperature control – output terms
The PID temperature control is found under Configuration – PID tab.
This screen will show the 3 temperature zones. Each zone will have a live P, I, and D term
(i.e. the mathematical output resulting from the current Set Point temperature, current
actual temperature, and the PID gains for that zone) and the actual temperature reading
(shown to the nearest 0.01 deg C).
