Abstract
In mail-weighing machines the values determined by a weight measuring device (20) are supplied in digital form to a programmable set-value store (27). The set-value store (27) and the codifier (23) supplying the digital, measured values are connected to the display device (24) via a first multiplexer (26) which alternatively supplies to the display device (24) the output signal (25) of the codifier (23) or that of the set-value store (27). In a manually-actuable selector device (38), different postage tariffs can be set which conform to different groups of addresses of the set-value store. The output of the first multiplexer (26) is one input to a second multiplexer (31). A time clock (32) or other source of information is connected to the other input of the second multiplexer (31). A sensor (34) controls the second multiplexer (31) so that the second multiplexer (31) so that the second multiplexer (31) supplies the signal from the first multiplexer (26) to the display device (24) during a weighing operation and the signal from the time clock (32) at other times.
