A method for testing a measuring bridge, the measuring bridge arrangement, the test arrangement for testing a measuring bridge, a method for producing a tested measuring bridges arrangement and computer program
A method (500) for testing a measuring bridge (210; 310) with four resistive elements (212 – 218; 312 – 318), at least one first supply connection (222; 322), a first measuring signal connection (232, 332) and a second measuring signal connection (236, 336), comprising the steps of:The measuring bridge (210; 310) in four different operating states, the different operating points of the measuring bridge, and detecting a each operating state associated measured value;Characterizing the four resistive elements (212 – 218; 312 – 318) of the measuring bridge circuit (210; 310) based on the detected measured values,in a first operating state, the measuring bridge (210; 310) over the at least one supply connection (222; 322) is fed,wherein, in a second operating condition, the measuring bridge (210; 310) via the first measuring signal connection (232, 332) is fed,wherein, in a third operating state, the measuring bridge (210; 310) via the second measuring signal connection (236, 336) is fed, andwherein, in a fourth operating state of a bypass switching element (252, 254; 352, 354), comprising a current path parallel to one of the resistive elements of the measuring bridge (210; 310), is activated.
