Abstract
A test module for a base module of a vibronic measuring system includes: a carrier element operable to oscillate when excited with an excitation frequency made of metal and/or plastics material; and at least one test element mechanically connected to the carrier element for producing a magnetic field, wherein the at least one test element is a permanent magnet, wherein the test module is designed to be inserted into the base module and to be releasably mechanically connected thereto such that the test module is locked in the base module or is immovable and/or such that the first element is held within the base module at a predefined testing position.

A test module for a base module of a vibronic measuring system and/or measuring-system electronics, wherein the measuring-system electronics are electrically connected to the base module, and wherein the vibronic measuring system is a modular Coriolis mass flow meter, the test module comprising:
- a carrier element configured to oscillate when excited with an excitation frequency of between 100 and 950 Hz, wherein the carrier element is made of metal and/or plastics material;
- and
- at least one electrical and/or magnetic and/or electronic test element mechanically connected to the carrier element for generating a magnetic field, wherein the at least one test element is a permanent magnet, and wherein the at least one test element includes a first test element,
- wherein the test module is configured to be inserted into the base module and to be releasably mechanically connected thereto such that the test module is locked in the base module or is immovable and/or that the first test element is held within the base module at a predetermined first test position.
