Abstract: A system for weighing a load that uses a weighing apparatus comprising a plurality of load cells (1), a means for receiving a load supported by said load cells, a means associated with each load cell (1) to supply a digital representation of the load on each load cell, said load cells being connected together to form a communication network, wherein a digital representation of the load on each load cell (1) is generated, a correction coefficient Xj of said digital representation for each load cell (1) is determined, said correction coefficient Xj is stored in the respective load cell (1) and the gain of each load cell is varied according to its correction coefficient Xj to generate a correct digital representation of the load for each load cell (1).
