After performing the above operation, the user can place the material object
(weight or material) with known weight in the appropriate position on the scale
body, and then perform the loading point calibration according to the following

6.2 Calculation method calibration
The calibration of calculation method can be completed by parameter F30. The
calibration coefficient of the parameter is obtained by theoretical calculation
method, and the calculation formula is as follows:
Calibration factor = sum of sensor range / sensor sensitivity coefficient
The sum of sensor ranges refers to the cumulative sum of all sensor ranges
on the scale, and the units used are consistent with those used in calibration.If
three 10 ton sensors are used, the sensitivity coefficient is 2.0mv/v, and the
calibration value is 1kg, then the calibration coefficient is 3×10000÷2.0 = 15000
