Abstract:
1. A method of evaluating functionality of an electrosurgical generator which delivers electrosurgical output power established by an output current and an output voltage, the electrosurgical generator including a control processor which controls the delivery of the electrosurgical output power and also including a monitor processor which monitors one of performance or functions of the electrosurgical generator, comprising: sensing the output voltage and the output current; calculating with a first computation a first value related to the output power delivered by using the sensed output current and the sensed output voltage; calculating with a second computation separate from the first computation a second value related to the output power delivered by using the sensed output current and the sensed output voltage; comparing the first and second values; indicating an error condition when the first and second values differ by a predetermined amount; performing the first calculation using the control processor; and performing the second calculation using the monitor processor.
