Claim 0:
1. A control method for use in a plating apparatus that supplies a current from a rectifier to a substrate to plate the substrate, the method comprising:
a step of outputting a current with a first current value from the rectifier, in a state where the substrate and a substrate holder holding the substrate are not electrically connected to the rectifier;
a step of acquiring an output voltage value of the rectifier;
a step of comparing the output voltage value with a predetermined reference voltage value;
a step of determining whether a short circuit does not occur in a circuit for connecting the rectifier and the substrate, in a case where the output voltage value is higher than the reference voltage value;
a step of determining whether the short circuit occurs in the circuit for connecting the rectifier and the substrate, in a case where the output voltage value is lower than the reference voltage value; and
a step of electrically connecting the substrate and the substrate holder holding the substrate to the rectifier and performing plating processing of the substrate in response to determining that the short circuit does not occur in the circuit for connecting the rectifier and the substrate, wherein the plating processing of the substrate is performed by outputting a current with a second current value from the rectifier, wherein the first current value is smaller than the second current value.
