If an oscillation persists, increase the proportional band. The switch must be located in the immediate vicinity of the instrument and must be within easy reach of the operator. This will allow the controller to be put into service more quickly and will avoid certain problems which may mistakenly be interpreted as malfunctions or limitations of the controller. PID parameters are calculated by measuring overshoot and the time needed to reach peak.
