Between pressing plate 3 and lower platen and mobile device 4；
(3) associated control parameters of pressure apparatus 5 are adjusted, load cell 1,2 center of standard dynamometer need to be in same vertical
On line, it is ensured that the steady stress of pressure apparatus first answers manual pressure to the distance between the load cell 1 and 3 bottom of top board to be
When 5.0mm~10.0 mm, stop manual pressure, afterburner process will delay, to read；
(4) when carrying out calibration reading, last position of decimal point is read as far as possible, it is ensured that summed data error is minimized, with
Guarantee to ignore completely when summation therefore and bring global error；By pressure source 6 apply pressure, make standard dynamometer 2,
1 stress of load cell, the calibration data of pickup；
(5) above-mentioned steps (1)-(4) are respectively adopted in remaining load cell 1 again to calibrate, finally find out more sensors
