0.01
Enter the process controller proportional gain. Quick control
is obtained at high amplification. However, if amplification is
too high, the process may become unstable.
Parameter

999.0 s
Enter the process controller integral time. Obtain quick con-
trol through a short integral time, though if the integral time
is too short, the process becomes unstable. An excessively
long integral time disables the integral action.
