A weighing device for a combination scale includes a force-sensing unit for converting a weight acting on a load sensor of the force-sensing unit into an analog electrical signal and an analog/digital converter to which the analog electrical signal is fed and which converts the analog electrical signal into a digital electrical signal. the weighing device further includes a controller for controlling the analog/digital converter and for additional digital processing of the digital values of the digital electrical signal fed to it. The weighing device has a synchronization output which is connected to the controller or to the analog/digital converter and to which a synchronization signal is fed that includes at least the information of the starting time points of the individual conversion processes performed by the analog/digital converter unit for determining a digital value of the digital electrical signal, and/or the weighing device has a synchronization input connected to the controller (13) or the analog/digital converter to which an external synchronization signal can be fed that includes at least the information of one or more desired starting time points for a conversion process to be performed by the analog/digital converter for determining a digital value of the digital electrical signal.
