Systems and methods for performing a self-verification system test upon activation of an electrosurgical generator are described. The systems and methods allow for enhancing surgical outcomes by providing generators having accurate RF energy generation, measurement, calibration and self-testing system. This is achieved through implementation of an automated self-verification process at a power start-up of the generator, which allows for rapidly identifying a potential generator issue prior to any use of a connected electrosurgical instrument or supply of any RF energy to the tissue or vessel through the electrosurgical instrument. Additionally, one or more internal impedance loads are integrated within the electrosurgical generator. The internal impedance loads with multiple configurations are utilized to verify the voltage, current, power, and/or phase measurements of the generator. By incorporating or integrating the self-verification process and its related hardware resources within the electrosurgical generator, many improvements in outcome of pre-surgical procedures may be achieved.
