Abstract: In present-day laboratory work, the largest proportion of the time goes on operations at the laboratory balance. A laboratory balance (1) is therefore provided with an interface (19), with which the laboratory balance (1) can communicate with all the other devices customary in a laboratory. By means of the interface (19), command data as well as weighing-specific data can be transferred from the laboratory balance (1) to the other devices. The other devices can further process the weighing-specific data dependent on the command data, for instance. Furthermore, the other devices can transfer data reflecting the work results to the laboratory balance (1) by means of the interface. Furthermore, the other devices can also transfer control commands to the laboratory balance (1), which in the laboratory balance (1), depending on the evaluation of the weighing-specific data, release or block functions in the laboratory balance (1).
