yc2, wherein fhIndicate that preset x-axis direction center of gravity deviation trims the factor, fvIndicate preset y-axis direction center of gravity deviation trim because
Son, w indicate the length of the scale to be corrected, and h indicates the width of the scale to be corrected.
10. according to the method described in claim 5, it is characterized in that, being sat according to the theoretical barycentric coodinates, the current center of gravity
Mark and preset calibration Rule of judgment up to standard, judge the preset calibrations slot this calibration whether step up to standard, comprising:
According to formula fiveObtain the error D of the actual center gravity coordinate, wherein
xs2The abscissa of first index slot or second index slot that are calibrated for this, ys2Described in being calibrated for this
The ordinate of first index slot or second index slot, DthdFor preset allowable error value；As D < DthdWhen, the reality
The error D of barycentric coodinates is less than the preset allowable error value Dthd, this calibration is up to standard, as D >=DthdWhen, the practical weight
The error D of heart coordinate is equal to or more than the preset allowable error value Dthd, this calibration is up to standard.
11. according to the method described in claim 5, it is characterized in that, the scaling board be rectangle, the preset coordinate system, with
The geometric center of the scaling board be origin, using the direction parallel with the length of the scaling board as x-axis direction, with the calibration
The parallel direction of the width of plate is y-axis direction.
12. according to the method described in claim 5, it is characterized in that, clump weight to be placed on to the current choosing on the scaling board
Determine the step on index slot, comprising:
The surface of current selected index slot, release are moved to by light rope and with the clump weight of the light rope connection by mobile mechanism
The light rope is so that the clump weight presses to the scaling board.
