Abstract
A method for monitoring a high resistance condition at an instrument terminal of an electrosurgical generator, which includes current and voltage measuring devices for determining a current and a voltage at the terminal to determine the high resistance condition, and includes a calculation device connected to the measuring devices which is configured to evaluate the determined current and voltage, including: determining a crest factor value from the current and/or voltage, wherein the crest factor value describes a ratio of a peak value to an effective value of the current and/or voltage; comparing the determined crest factor value with a comparison value by means of a comparison device, wherein the comparison value is stored in a data storage device; and signaling a high resistance condition with a signaling device when the determined crest factor reaches or exceeds the predetermined crest factor comparison value. Also, an electrosurgical generator and electrosurgical generator system.
