PURPOSE: A method is provided to be capable of automatically setting relay elements by use of current measured at an ammeter. CONSTITUTION: Read is the current applied to an electric device(S10). The current is used to calculate a starting current(Is) needed for driving the electric device, a regulated current(In) needed at a stable operation state of the electric device, and a starting time(It) needed when the electric device reaches a stable running state(S20). An established value of a relay element is calculated and stored according to an established factor using the calculated starting current, regulated circuit and starting time(S30,S40).
