Abstract

An electrosurgical apparatus includes a radio frequency (RF) power source for supplying an RF signal to an object to be cauterized through a treatment tool and an electrode plate. A dummy load with a certain impedance is coupled in the current path from an active terminal to which the treatment tool is connected to the check terminal connectable to an electrode plate. Before electrosurgical treatment, the dummy load is connected to the active terminal and the check terminal. An actual RF signal flowing through the dummy load is detected and compared with a predetermined RF signal from the RF power source.
