Test module, test system and test arrangement for a base module and/or a measuring system electronics unit of a modular vibratory measuring system

A test arrangement, comprising:

• a test system for testing a base module of a vibronic measuring system and/or a measuring system electronics of the vibronic measuring system electrically connected to the base module, the test system including:
• a test module for the base module of the vibronic measuring system, the test module including:
• a carrier element;
• and
• a first test element mechanically connected to the carrier element for generating and/or detecting a magnetic field,
• wherein the test module is configured to be inserted into the base module and to be detachably mechanically connected thereto again;
• and
• a test system electronics that is electrically connected to the test module;
• and
• the base module of the vibronic measuring system,
• wherein the base module has a protective housing with a chamber at least partially wrapped by a housing wall and a first electrical coil that is placed inside the chamber of the protective housing and which is at least indirectly mechanically connected to the housing wall and electrically connected to the measuring system electronics, and
• wherein the test module of the test system is inserted into the base module and is mechanically fixedly connected thereto, but nevertheless releasably connected again, in such a manner that the carrier element and the first test element are placed within the chamber.
