Manual PID tuning is done by setting the reset time to its maximum value and the rate to zero and increasing the gain until the loop oscillates at a constant amplitude. (When the response to an error correction occurs quickly a larger gain can be used. If response is slow a relatively small gain is desirable).

How do I manually tune my PID?
To tune your PID controller manually, first the integral and derivative gains are set to zero. Increase the proportional gain until you observe oscillation in the output. Your proportional gain should then be set to roughly half this value.
What are different methods of PID tuning?
In broad terms, there are three PID tuning methods for determining the optimal combination of these settings: heuristic tuning, rule-based tuning, and model-based tuning. Each method has its pros and cons.
What are the PID tuning parameters?
PID is an acronym for Proportional, Integral, and Derivative. These parameters can be used, adjusted, and controlled individually and collectively. You can have, for example, a P controller, a PI controller, or a PID controller.
How to calculate PID tuning parameters?
The PID formula weights the proportional term by a factor of P, the integral term by a factor of P/TI, and the derivative term by a factor of P.TD where P is the controller gain, TI is the integral time, and TD is the derivative time.
