Mainly according to its scale division value, maximum weighing to the assay calibration of electronic scales at present, by standard test weight, the points of load such as its zero load, minimum weighing, limits of error turning point, 1/2nd maximum weighings, maximum weighing are carried out to assay calibration, also need in addition the flickering point of each point of load to carry out assay calibration.In whole assay calibration process, need to have the counterweight of various different sizes to support.
Some are located in the periodic verification calibration process of electronic scales of the wide range in building, have the following disadvantages:
1, counterweight is the sole criterion of quality transmission of quantity value, standard test weight is carrying out wide range electronic scales in the process of assay calibration, change because environment, the factor such as artificial can make the mass formation of standard test weight, introduce larger uncertainty to the transmission of quality value.
2,, while using standard test weight to carry out assay calibration to electronic scales, owing to can only being confined to artificial assay calibration (artificially loading and reading), can not well realize digitizing, intellectuality; Meanwhile, human factor also can be brought a lot of uncertain factors, thereby affects final assay calibration result.
3, in the time that the electronic scales of a large amount of scale scopes is carried out to assay calibration, the loading of large mass weight and unloading will bring larger trouble to assay calibration process, the process such as move brought extremely heavy manual labor to assay calibration personnel as: load/unload, the position of large quality load.

Brief description of the drawings
Fig. 1 is principle assumption diagram of the present utility model,
1-the first electromagnet, 2-the second electromagnet, 3-the 3rd electromagnet, 4-power output unit, 5-photodetector.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Principle of the present utility model is: pass through electromagnetic induction principle, convert standard electric signal to electromagnetic signal, by magneticaction, electromagnetic signal is converted into power value signal again, and then power value signal is amounted to into mass value output, this process is applied in the assay calibration process of electronic scales, digitizing, intelligentized assay calibration process will come true.
As shown in Figure 1, the first electromagnet (fixing) is the magnet that repels each other with the second electromagnet, along with the variation of the alternating current loading on two blocks of electromagnet, on the second electromagnet, produce the downward thrust of direction that size changes with the curent change loading on the first electromagnet and the second electromagnet, this thrust is exported by power output unit.
The second electromagnet 2 and the 3rd electromagnet 3(fix) under original state, be two like magnetic poles repel each other, along with the variation of loading current on two blocks of electromagnet, the 3rd electromagnet 3 produces the mass value that the big or small direction changing with loading current on the two thrust upwards produces for neutralizing the second electromagnet 2 and power output unit 4 self gravitations.Photodetector 5 changes for the slight distance of determining the relative position between the first electromagnet 1 and the second electromagnet 2.
In actual use, the 3rd electromagnet 3 and the second electromagnet 2 can be also that there is a natural attraction between the sexes magnet, produces to the second electromagnet downward pulling force is less than standard output mass force part to compensate the downward thrust being produced between the first electromagnet and the second electromagnet with the 3rd electromagnet.
The quantity of the 3rd electromagnet can be multiple and along uniform outside application of force post, can select suitable quantity according to actual conditions, if the quantity of electromagnet is three, these three electromagnet can be positioned on three summits of equilateral triangle so; If the quantity of electromagnet is four, these four electromagnet can be positioned on foursquare four summits so, the not unbalance loading of small power that guarantee applies like this.The quantity of the 3rd electromagnet is more, and capable of regulating orientation is larger, and can realize the loading of the small power that is less than tested electronic scales scale division value 1/10th, realizes the measurement of flickering point.
In the assay calibration process of electronic scales, this device is fixed at the enterprising rower of standard measure of pin-point accuracy grade, the same mass value of exporting by multiple positions that photodetector is shown is demarcated, obtain corresponding many groups of first electromagnet 1 corresponding with position and the second electromagnet 2 and the 3rd electromagnet 3 electric current input values, also can demarcate on this basis in addition tested electronic scales tenth of the point degree value (mass value) corresponding to the 3rd electromagnet 3 electric current small variation, for the assay calibration to tested electronic scales flickering point.Then at the scene tested electronic scales is carried out in assay calibration process, reappear corresponding electric current on three electromagnet corresponding to a certain position (being determined by photodetector 5), just reappear corresponding mass value, reappear the electric current microvariations on the 3rd electromagnet 3 simultaneously, realize flickering point mass value assay calibration.By the reproduction of the calibrating point that specifies in multiple mass value codes, just complete the on-site proving calibration of electronic scales.
As: in the time that metrological service's demarcation output quality is a kg, scalar quantity is as follows:
By demarcating the above data of the quality of a kg obtaining on the standard measure in metrological service's pin-point accuracy grade, at the scene in the assay calibration process of electronic scales, this device is arranged on the electronic balance body that needs assay calibration by support, adjusting pole, when the lower surface of power output unit contacts with scale body, the position showing as photodetector is e, that loads corresponding electric current (m4 to respectively three electromagnet, n4, e1) just can be to examined electronic scales reproduction a kg, in addition, on this basis, finely tune respectively the voltage (e11 loading on the 3rd electromagnet, e12, e13 ...), complete the assay calibration of flickering point.
This cover core apparatus configures the multiple support that can fold, and just can well realize the assay calibration process of wide range electronic scales.Can be easy to and well this device be demarcated in metering mechanism, then applying in the electronic scales assay calibration process of the large quality of metrological personnel to scene, thereby solving these weak points that exist in existing assay calibration process.
