1.在对试验机示值进行标定时,要依照设备数显部分说明书中的程序逐步操作,需注意的是当标定第一个点时,必须将油缸上升到试验机上压板与标准测力计待要接触时,再按下“确认”键,以减小油缸上升时产生的摩擦力对示值的影响。并且在标定第一个到第二个标定点时,如果是手动加荷,加荷速度一定要掌握到末位数字逐字变化,如果是自动加荷,可将加荷速度调为
1. When calibrating the indication value of the testing machine, it should be operated step by step according to the procedures in the manual of the digital part of the equipment. It should be noted that when calibrating the first point, the cylinder must be raised to the testing machine. The pressure plate and the standard dynamometer To be contacted, press the “” button to reduce the influence of the friction generated when the cylinder is rising. And in the calibration of the first to the second calibration point, if it is manually loaded, the loading speed must grasp the last digits of the word change, if it is automatic loading, the loading speed can be adjusted to
