Claims (1)
Ｖと設定値ＳＰとが入力され、制御出力Ｃ・ＯＵ
Ｔを前記プロセス２に送出する制御部１と、 押しボタンスイツチ等からの操作出力ＲＵＮを
受けると、まず、定値出力ＯＰ・ＯＵＴを前記プ
ロセス２に送出し、この定値出力ＯＰ・ＯＵＴに
よるオープンループ制御を行い、所定時間経過後
に該定値出力ＯＰ・ＯＵＴをオフとし、代わりに
、前記制御部１に制御指令ＲＵＮ・Ｄを出力して
前記制御出力Ｃ・ＯＵＴによるクローズドループ
制御を行わせる定値制御部４とを有することを特
徴とする調節計。[Scope of claim for utility model registration] Process amount P from process 2 to be controlled
V and set value SP are input, and the control output C・OU
Upon receiving the operation output RUN from a push button switch, etc., the control unit 1 sends T to the process 2, and first sends the fixed value output OP/OUT to the process 2, and an open loop is created by the fixed value output OP/OUT. Fixed value control that performs control, turns off the fixed value output OP/OUT after a predetermined time has elapsed, and instead outputs a control command RUN/D to the control unit 1 to perform closed loop control using the control output C/OUT. A controller characterized in that it has a section 4.
