Abstract
A monitor for the return electrode of electrosurgery apparatus has three contacts in a socket that connect with two or three contacts on a plug connected to the return electrode. One pair of contacts in the socket is connected across an oscillator that provides an output to a first primary winding of the transformer when there is a low impedance between the contacts. Another pair of contacts is connected across a second primary, winding and produces a loading on the transformer when short circuited by the return electrode, A detector is connected to the secondary winding of the transformer and produces an alarm and disable signal if the signal on the secondary winding falls below a lower limit or exceeds an upper limit,
