1. A method of purging an electrosurgical system comprising:

  • activating a radiofrequency (RF) output at a level that does not cause heating or damage to a patient or user in the event of unintended contact;

    activating a fluid delivery system for delivering an electrically conductive irrigation fluid to an active electrode and a return electrode;

    monitoring current between the active electrode and the return electrode;

    detecting a threshold current level indicative of the presence of a sufficient amount of the electrically conductive irrigation fluid adjacent the active electrode and the return electrode; and

    causing the RF output and fluid delivery system to deactivate.
