Abstract
A check weight () that is used to check a gravimetric measuring instrument, specifically a balance, or to check a further weight, is provided with a means of identification. This marking which is applied on the outside surface of the check weight includes a permanently affixed machine-readable identification code () which makes the specific weight piece individually recognizable. This opens the possibility for a method whereby an individually identifiable check weight can be traced back in time. A system for tracing check weights back in time includes one or more reader devices () that serve to record the marking, one or more processors () wherein the machine-readable identification code can be converted back into an identification code that can be electronically processed, and one or more data storage units, in particular a database () serving to store at least the data contained in the identification code.
