Abstract
An operating table used with electrosurgery equipment has a high impedance static discharge resistor connected between the table and ground. A monitor is connected across the resistor and is responsive to a change in resistance between the table and ground which is indicative of bypassing or failure of the resistor and which is independent of operation of the electrosurgery equipment. The monitor provides an output to an alarm and also disables the electrosurgery equipment in response to such a change in resistance.
