Abstract

The invention comprises a balance (1) with at least one digital weighing cell (2, 3, 4, 5) and an evaluation unit connected to the balance. The digital weighing cell (2, 3, 4, 5) is provided with memory elements (12, 13, 14, 15) in which the weighing cell parameters and the system parameters of the balance (1) or code numbers formed thereof are stored in an unmanipulatable manner by known methods such as audit trail counters, for example. The evaluation device is embodied as a program controlled data processing device (7) and is directly connected to the balance (1) or weighing cells (2, 3, 4, 5) provided therein. The measured data of the digital weighing cells (2, 3, 4, 5) which are calibratable and/or not calibratable are read out by the program-controlled data processing device (7) during each weighing process (7), in addition to the stored weighing cell parameters and system parameters of the balance (1) or the codes formed thereof. These data are compared with the system parameters or codes formed thereof which were fed into the program-controlled data processing device (7). If a deviation is ascertained, the weighing process is terminated or at least the measuring data which are calibratable are displayed with the ascertained deviation, documented, signaled and/or recorded.
