Test system for testing electrical connection of unencumbered of structural elements

摘要

The test unit is provided with a unit (6) for the simultaneous current loading of several contact pieces (31-36), and a contacting unit (54) contacts at least one test point (41-46). A measuring unit (51) determines the current flow between the loading unit and the contacting unit. The current loading unit (6) electrically contacts the contact pieces with the contact points (61-66). All the contact points are connected in the current loading unit with their current supply (52), and together across resistances (71-77). These resistances in the loading unit are smaller between the contact points (61-66), than the resistances of the materials between the conductor paths (21-26).
