Abstract

An instrument test arrangement is specified, which is preferably equipped for medical instruments for argon plasma coagulation. The instrument test arrangement comprises an electrode arrangement, comprising at least one test electrode. In a preferred embodiment, a test electrode is thereby connected to two neutral conductors of a neutral conductor cable or device, wherein the neutral conductors are insulated from one another, and wherein the first coupling impedance between the test electrode and the first neutral conductor and the second coupling impedance between the test electrode and the second neutral conductor are equal or at most slightly different, so that a split circuit, which is assigned to a neutral electrode arrangement, does not trigger due to the strike of a test spark or arc.
