    摘要: A drying balance is disclosed with a means (11) for supplying energy for the drying of material to be weighed located on the balance scale (6,16) and with a digital evaluating unit (23,24,25) for calculating the moisture content from the measured weight loss of the specimen and for determining the end point of the drying in which balance the digital evaluating unit (23,24,25) calculates the inflection point from the chronological course of the weight loss and derives the criterion for determining the final point therefrom. The criterion for the final point consists in that the slope of the drying curve drops below a certain value which is derived from the coordinates or the slope of the drying curve at the inflection point.

    摘要: The invention suggests for an electronic balance with a balance scale (1), with a parallel guide for the balance scale (1), with at least one sensor which measures the torques transferred from the balance scale (1) to the parallel guide, with storage means in the electronic circuitry of the balance in which means the magnitude of the corner-load inaccuracies of the parallel guide is stored in the form of corner-load correction factors and with switching means or program parts in the electronic circuitry of the balance which correct the weight value outputted from the measuring system on the basis of the output signals of the sensor or sensors and of the stored corner-load correction factors that controllable signals (10-13) are provided which designate the corners and sides of the balance scale (1). The signals can be formed by light sources adjacent to the balance scale (1) or in the corners or on the sides of the display field (9). The use of individual segments of the 7-segment numbers (3) of the balance display is preferred. An operator control can be achieved with these signals when readjusting the corner-load freedom of the balance.

    摘要: The invention discloses an electronic balance comprising a measured value receiver (23) and an electronic evaluation unit (14) having a digital display (10) and an analog display (6), whereby both displays are controlled by the electronic evaluation unit (14). A digital input keyboard (12) is used for inputting the set weight value of a loading. The electronic evaluation unit (14) contains a memory (15) and an arithmetic unit (16) which permit the values indicated in the digital display (10) and in the analog display (6) to be differentiated against each other by the amount stored in the memory (15) so that during a loading procedure the digital display (10) runs from the negative set weight value to 0g and the analog display (6) from 0% to 100%. The analog display (6) consists of adjacent bars (7) which can be shited in their lightness, whereby the length of the individual bars continuously decreases from 0% to 100% of the set weight value, and continuously increases again over 100% of the set weight value.

    摘要: In known methods of initializing a balance with counting scale a given quantity of the pieces to be counted is placed on the balance at the same time and the average individual weight is calculated therefrom and used as a base for the following piece counts. In contrast thereto, the invention suggests that the pieces be placed individually on the balance and that the standstill of the balance be waited for after each placing of a piece. This makes it possible to also calculate the standard deviation in addition to the average value and statements concerning the counting precision can be made which are based on known statistical laws, so that counting errors can be avoided.
