ABSTRACT:
A PID controlling meter is provided with unit for displaying an amount of operation representing the sum total of the bias constant and the operation result of three terms, i.e., a proportional term, an integrating term and differentiating term each of which is a function of deviation. The meter also has a constant setting unit for setting displayed amount of operation as a control parameter; unit for displaying set values of the constant setting a unit; a unit for reading the set values of the constant setting unit when a power source is closed; and a unit for determining bias constant when the power source is closed on the basis of the constant set values read by the reading unit.
