Abstract

The method disclosed herein permits the operator of an electrosurgical device to move a safety switch-off threshold for a contact resistance at a neutral electrode from a first value to a second and slightly higher value. This way, for patients with a relatively high resistance yielding a somewhat elevated contact resistance despite correct attachment of the neutral electrode, uninterrupted operation of the device is achievable.
