Abstract

To provide the user of an RF-surgical instrument with a non-hazardous short test operation, for example so as to test the ignitability of an argon plasma probe, provision is made for an instrument test arrangement, which is installed into a feeding medical device or into a neutral conductor connecting cable or which is provided as plug adapter, which is to be plugged between the device and the neutral conductor connecting cable. The instrument test arrangement comprises at least one or, better yet, two ignition test electrodes, which are connected to conductors of the device or of the neutral conductor cable, preferably via impedance components. The ignition test electrodes can be accessed insofar as a spark can be created simultaneously to both ignition test electrodes by means of an operational probe or an instrument.
