摘要

The experimental device (1) comprises an electronic circuit arrangement (20) with multiple circuits, which are opened and closed between a primary potential (31) and a secondary potential (32) with a circuit element (40) of the circuit arrangement. A housing (10) is provided, which encases the circuit arrangement in an electrically insulating manner. An experimental field (60) is formed on an outer side of the housing with an individual contact (61), which is connected with the primary potential and with multiple other individual contacts (62) connected with each of the circuit elements.
