1. A surgical system comprising:
a control circuit; and
an output circuit coupled to the control circuit and configured to deliver electrosurgical energy to an output terminal for delivery to a patient, the output terminal configured to couple to an electrosurgical device having two electrodes,
wherein the control circuit is configured to:
compare a first measured impedance value of biological tissue in electrical communication with the two electrodes of the electrosurgical device to a first threshold value;
initiate a timer when the first measured impedance value is less than or equal to the first threshold value;
compare a second measured impedance value of the tissue between the two electrodes to a second threshold value, wherein the second threshold value is greater than the first threshold value; and
continue the delivery of electrosurgical energy when the second measured impedance value is less than the second threshold value and the timer has not met a time limit.
