1. A surgical generator configured to generate and provide a therapeutic signal to biological tissue in electrical communication with a surgical instrument, the surgical generator comprising:
a control circuit in communication with an electrical-energy source, the electrical-energy source electrically coupled to the instrument and configured to generate the therapeutic signal, the control circuit configured to:
control an energy delivery of the therapeutic signal provided to the biological tissue during at least one of an interrogation phase and a first drying phase, the interrogation phase being to obtain electrical properties of the biological tissue, and the first drying phase being to dry or desiccate the biological tissue;
after completion of at least the first drying phase, compare an amount of energy delivered to the biological tissue during the at least one of the interrogation phase and the first drying phase to a threshold energy value; and
adjust the delivery of the therapeutic signal based on the comparison and continue delivery of the therapeutic signal,
wherein the control circuit configured to adjust delivery of the therapeutic signal based on the comparison is further configured to:
control delivery of the energy of the therapeutic signal provided to the biological tissue in order to perform a second drying phase if the amount of energy delivered exceeds the threshold energy value during the at least one of the interrogation phase and the first drying phase,
wherein a power ramp rate for the second drying phase is less than a power ramp rate for the first drying phase.
