Patent ID: 7151230

Claim:
A method of weighing a load by means of a weighing apparatus comprising a plurality of load cells arranged underneath a load platform supported on said load cells, said load cells being connected together to form a communication network, said method comprising generating a digital representation of the load on each load cell, determining a correction coefficient X j of said digital representation for each load cell, storing said correction coefficient X j in the respective load cell and varying the gain of each load cell on the basis of the respective correction coefficient X j to generate a correct digital representation of the load for each cell, each load cell detecting its own address I and checking that said address I is other than zero, whenever said weighing apparatus switches on, wherein if said address I is the same as zero, the load cell generates and stores its own address I consisting of a number selected at random from a range comprised between n+1 and m, n being the maximum number of load cells for which said apparatus is designed.
