    Abstract: The output signal from a measuring transducer in a force-measuring device is processed by filtering a measuring signal (ms), representing a load that is acting on the transducer, to suppress interfering signal portions caused by extraneous influences including mechanical disturbances, or changes of the load. The measuring signal (msE) passes through a first delay element (141A) to a measurement value unit (145) which holds the value of the currently received measuring signal (msE), a mean value based on the most recent values of the measuring signal, or an expected value (msE) based on the most recent values of the measuring signal. The measuring signal (msE) is monitored for signal disturbances using a first detector module (151). After detection, a switching means (142) is actuated and the output signal (msX) of the measurement value unit is processed further, if applicable, and sent to the output end of the device, instead of the currently received measuring signal (msE).

    Abstract: A method, an arrangement and a program process a measurement signal generated in a measurement transducer of an electronic force-measuring device, particularly a balance. The generated measurement signal corresponds to the force acting on the transducer. The measurement signal is entered directly or by way of a pre-processing stage into a display function which assigns corresponding output values to the values of the measurement signal. The output values are subsequently presented in a display or passed on for further processing. The input range of the display function contains a capture range, so that the values of the measurement signal that lie within the capture range are assigned a common output value by the display function, and the position of the capture range within the input range is controlled dependent on the generated measurement signal.

    Abstract: The force-measuring device includes a measuring unit and a reference unit, the latter serving to deliver a reference quantity, a reference current (IREF) or a reference voltage (UREF), through which the force (FMO) of a measurement object which is to be determined can be measured by the measuring unit. The reference unit is a force-measuring device which is loaded with a reference mass and which in accordance with the principle of electromagnetic force compensation generates a reference current (IREF) that can be regulated through a measuring- and regulating device in such that in a first reference coil which is held by a reference lever, the reference current (IREF) generates a magnetic field which cooperates with the magnetic field of a reference magnet. Through this cooperation a magnetic force is brought to bear on the reference lever. As a result, the force (FREF) of the reference mass which is likewise acting on the reference lever can be compensated by said magnetic force.

    Abstract: A method serves to correct drift phenomena, in particular creep effects, occurring in an electronic balance that has a measuring transducer through which a measuring signal is formed which is representative of a load applied to the force-measuring device. The measuring signal is delivered by way of an analog/digital converter to a signal-processing unit that is supported by at least one processor, said signal-processing unit being capable of compensating drift deviations, for which purpose the signal-processing unit, via the processor, accesses drift parameters that are stored in a memory unit and serve as basis for calculating a time-dependent correction value by which the drift error of the measuring signal (ms) is corrected. At time intervals that are either controlled automatically or chosen by the user, new optimized values for the drift parameters are determined automatically by the processor and the signal-processing unit under the control of an optimization program that is stored in the memory unit, and the new optimized values are filed in the memory unit.

    Abstract: A method serves to process output signal of a measuring transducer in a force-measuring device, in particular in a balance, wherein the measuring transducer produces a measuring signal representative of a load acting on the device and the measuring signal is filtered in a variable analog filter and/or, after processing in an analog/digital converter, the measuring signal is filtered in a variable digital filter, in order to remove unwanted signal components that are caused by disturbances affecting the force-measuring device, in particular by changes in the weighing load. The measuring signal is monitored in regard to the occurrence of a change in the weighing load and after a load change has been detected, at least one filter parameter of the filter is reset and then varied as a function of time in accordance with a prescribed time profile fc(t), so that the filter is opened after a load change has been detected and then closed again to the point where a predefined filter characteristic has been attained which is determined by the end value of the at least one filter parameter. By using this method, it is possible with simple measures to realize noticeably shortened transient settling times of the force-measuring device after a load change has occurred.
