摘要：
A control circuit for use with an electrosurgical system is disclosed. The control circuit is programmed to provide an electrosurgical signal comprising a plurality of pulses to first and second electrodes and receive a first reading of an impedance between the first and second electrodes. The control circuit is programmed to receive a second reading of the impedance between the first and second electrodes. The control circuit is programmed to determine a difference between the first and second readings and determine that a short circuit is present between the first and second electrodes based on a magnitude of the difference between the first reading and the second reading. The control circuit is programmed to generate a signal indicating the short circuit between the first and second electrodes.
