title: A simple and inexpensive method for measuring electrosurgical variables.
abstract: A simple circuit that demodulates the high-frequency output of an electrosurgical generator to proportional DC values can be employed to monitor generator voltage and electrosurgical current. An example of the use of the circuit in a urologic application is given. Employing this monitoring circuit, quantitative comparisons of electrosurgical equipment and performances can be made.
