PURPOSE:To regulate an electronic equipment at high speed, by increasing a set value counted by a counter in every drive of a regulating means and by lengthening the cycle of drive of the regulating means as the regulation makes its way. CONSTITUTION:A regulated part 67 such as a semifixed resistor, etc. of an electronic equipment is regulated by the axial rotation of a pulse motor 52 as a regulating means. The result of regulation is outputted to a measuring terminal 68 of the electronic equipment 66 as DC voltage. The rotation of the pulse motor 52 is controlled by a drive control means 85. As the count of a preset counter 36 goes up in every rotation of the pulse motor 52, the pulse cycle of a coincidence output 4 becomes longer and longer. The pulse motor 52 rotates fast immediately after the start of regulation, but as the regulation makes its way, it rotates at a low speed. |
