The results show that disc side face run-out results in brake torque variation by means of disc thickness variation.

结果表明：制动盘端面跳动最终以虚拟制动盘厚度变化形式引起制动力矩的波动。

If any of the measurements exceed the brake disc thickness variation specification, a new brake disc must be installed and the brake disc runout re-checked.

如果有任何测量值超过制动盘厚度变量规格时，则必须安装新的制动盘并且重新检查制动盘的失圆。

The system can be used in installing and debugging the disc and also in measuring the micro displacement of the object, the surface shape and thickness of the object, so it has fairly applied value.

本系统除可用于码盘的安装调试外，还可测量物体微位移、物体表面形貌及物体厚度，有很大的实用价值。
