the electric balance in fig1 consists of a support part 1 fixed to the housing to which part load receiver 2 is fastened in a vertically movable fashion via two rods 4 and 5 with articulations 6 . the load receiver carries load scale 3 in its upper part for receiving the material to be weighed and transmits the force corresponding to the mass of the weighed material via coupling element 9 with thin areas 12 and 13 to the shorter lever arm of transfer lever 7 . transfer lever 7 is mounted on support part 1 by cross spring joint 8 . the compensation force , produced by a current - carrying coil 11 in the air gap of permanent magnet system 10 attacks the longer level arm of transfer lever 7 . the magnitude of the compensation current is regulated in a known manner by position sensor 16 and controlled - gain amplifier 14 so that equilibrium prevails between the weight of the material to be weighed and the electromagnetic compensation of force . the compensation current produces a measuring voltage on precision resistor 15 which is fed to digitizer 17 . the digitalized result is taken over by digital signal processing unit 18 . the digital signal processing unit contains a storage area 20 which is shown as a shift register with twenty storage locations in the example shown . shift register 20 is timed by the remaining part 19 of the digital signal processing unit over lead 21 and at each timing pulse a new data record is taken via leads 22 and 23 and stored in the first ( the left one in the drawing ) storage location . at the same time the data record stored previously in the first storage location is taken into the second storage location the data record previously stored in the second storage location is taken into the third storage location , etc ., until the twentieth storage location , whose previously stored data record is erased . the data fed to the input of the shift register stems from sensors 24 and 25 and is prepared in associated signal shaping modules 26 and 27 . in the case of analog sensors these signal shaping modules consist , for example , of a digitizer with data store . in the case of sensors with a frequency analog output signal , such as , e . g ., quartz temperature sensors , they can consist of a counter . alternatively they may consist of ternary circuit stages for dividing the measuring frequency down to approximately 1 hz . this low frequency can then be determined by counting the periodic length with digital signal processing unit 19 . however , the data fed to the input of shift register 20 can also be determined ( over lead 29 ) by the digital signal processing unit from the output signal of measured value receiver ( elements 1 - 17 ). the measured data of sensors 24 and 25 could likewise be fed over signal shaping modules 26 and 27 directly to digital signal processing unit 19 and from there to the shift register , without the mode of operation changing . digital signal processing unit 19 has access over lead 28 to the individual storage locations of shift register 20 . it can take the individual data records , multiply them by weighting factors , calculate the necessary corrections for the output signal of measured value receiver ( elements 1 - 17 ) from the result and transmit the result into digital display 30 . the mode of operation given of this circuit can be explained with the examples in fig2 . this figure considers only the disturbance variable of temperature , which is measured by a single temperature sensor . only ten storage locations are assumed for the shift register . the upper part of fig2 shows the assumed course in time of the temperature as a curve , whereby the measure of time progresses form right to left . the current temperature ( line x 1 ) is stored in the first storage location of the shift register . the temperature x 2 which prevailed before a timing period , e . g . before one minute ago , is stored in the second storage location . temperature x 3 which prevailed before two timing periods ago is stored in the third storage location , etc . the assumed course of the curve thus shows a temperature rise in the last two timing periods and an approximately constant temperature in the time before them . if a thermally inert system is to be corrected , then the sensitivity in fig1 which is basically determined by the relatively large and heavy permanent magnet 10 , the upper set of weighting factors in fig2 is used . the central storage locations are weighted more heavily and the front and the back storage locations , i . e . the most recent and the oldest data , are weighted less . thus , the temperature rise assumed in fig2 takes effect only gradually in the last two timing periods and in a time - delayed manner in the magnitude of the temperature - dependent correction , precisely as the temperature - dependent component part , the magnet , warms up only gradually . the lower set of weighting factors in fig2 is intended for a thermally rapidly reacting system , e . g . in the measured value receiver of fig1 for the zero point , which is largely determined by thin articulations 6 and rods 4 and 5 . it is assumed in fig2 that the temperature sensor used reacts more slowly to a temperature change than the measured value receiver does . for this reason an extrapolation is performed from the stored historical measured values of the temperature sensor to the next measured value to be expected . a value is added to the most recent measured value x 1 , 3 / 4 of which results from the rise between the last two measured values ( x 1 - x 2 ) and 1 / 4 of which results form the rise between the last two measure values x 2 - x 3 : thus , the lower set of weighting factors in fig2 ( given without a standardizing factor ) represents an estimation and the temperature correction is performed at the estimated level as it will be measured by the temperature sensor in the next ( future ) timing periods . this example is intended to show that the use of properly selected weighing facts can also correct , to a certain extent , errors of the measured value receiver which occur more rapidly during changes in the disturbance variable than the sensor used can recognize . the time sets of weighing factors in fig2 are intended to show examples of different possibilities of the adaptation of the behavior in time of the sensor and of the measured value receiver . a great number of other groupings of weighting factors is possible . they must be determined in accordance with the special qualities of the sensor and the measured value receiver and implemented in accordance with the signal processing unit . just as the determination of the weighting factors must be performed in accordance with the specific balance , sensors 24 and 25 must also be selected according to the specific balance and according to the disturbance variables with the greatest effect . the following examples are also only intended to show the range of possibilities . moisture sensor 25 is attached to coil body 11 or in its vicinity and temperature sensor 24 &# 39 ; is attached to support part 1 fixed to the housing . the moisture effect of the coil winding is corrected from the data of the moisture sensor and the temperature error of the entire measured value receiver is corrected from the data of the temperature sensor . the weighting factors for the moisture effect are indicated as a function of the temperature dependent - behavior in time of the taking of moisture and the temperature - dependent variable of the taking of moisture and the temperature - dependent variable of the taking of water . a first temperature sensor 25 &# 34 ; is attached to coil body 11 and another temperature sensor 24 &# 34 ; is attached to the support part fixed to the housing . temperature sensor 24 &# 34 ; measures the average temperature of the measured value receiver , temperature sensor 25 &# 34 ; measures the temperature of the coil , and the difference of the two temperatures shows the load - dependent excess temperature of the coil . the temperature coefficient of the entire measured value receiver is corrected from the stored values of temperature sensor 24 &# 34 ; and the effect of the changed lever relationships on lever 7 resulting from the excess temperature of the coil and the changed field strength of permanent magnet system 10 are corrected from the different of the stored data of the two temperature sensors . only one temperature sensor 24 &# 39 ;&# 34 ; is present on support part 1 fixed to the housing . digital signal processing unit 19 calculates the power loss in coil 11 from the output signal of measured value receiver ( elements 1 - 17 ). the evaluation is performed as in example 2 . a measured value receiver consisting of a spring body with adhered - on wire stain gauges is associated with a temperature sensor and a moisture sensor in the vicinity of the spring body . the weight - dependent output signal of the measured value receiver is taken into the shift register along with the data of these two sensors . from the stored temperature values the temperature error of the measured value receiver ( e . g . the temperature coefficient of the elasticity modulus ) is corrected , the weighting factors for the effect of moisture are differently indicated according to the temperature , and in the third place the weighting factors of the stored load values are differently indicated according to the temperature to compensate for creep . the store requirement goes according to the clock rate with which the data is written in and passed on and according to the time required for which data is required for calculating the corrections . in order not to let the storage requirement become too large , it is recommended not to store a new value in the storage area for each new measured value from the measured value receiver . while the measured values from the measured value receiver are supplied anew approximately every second , it is sufficient in many instances if a new value is taken into the storage area approximately every minute . fig3 shows another possibility of saving storage locations , again using the example of a shift register . this shift register consists of a first partial area 20 &# 39 ; with 16 storage locations into which the data is introduced with the clock rate indicated in fig1 . the timing for the second partial area 20 &# 34 ;, which also and 16 storage locations , is reduced in fig3 by a factor of 4 by frequency divider 31 . the particular average value of the last four storage locations of the first partial area is transferred into the second partial area ( average value former 32 ). since this transfer only occurs at every fourth timing pulse of the first partial area , each value from the first partial area is precisely considered for transfer into the second partial area . the arrangement of the partial areas of the shift register shown in fig3 permits the data from a maximum of 4 × 16 + 16 = 80 timing periods of the timing of the first partial area to be stored with 16 + 16 = 32 storage locations . the fact that the older data is present only as an average value over four timing periods is generally not a problem , since a fine resolution in time is no longer so important for the earlier time periods . this division of the store demonstrated with the example of a shift register can also be transferred in an analogous manner to other storage organizations . after the balance is turned on , the storage area is empty at first and is only gradually filled with data . the method of operation provided and described above is therefore not yet possible . it is therefore advantageous to provide the balance in a known manner with a stand - by circuit in which the essential parts of the electronic components remain cut in and only the display and other component parts which would age the balance if they are on are cut off . in this instance data can be taken continuously into the storage area even during stand - by operation and correction of the measured value is immediately assured to ± 00 % after complete cut - in . if the balance is completely separated from its supply voltage and is cut in again , it is advantageous if further data is calculated from the first measured values of the sensors and stored in the empty locations of the storage area . this calculated data can not show the individual previous history of the balance before it was cut in , but it can be selected in such a manner that the start - up of the balance , which is conditioned by the cut - in , is approximately corrected at approximately constant temperature and moisture .
