如果使用分离的电流源和电压表来进行低电阻测量，则必须检查每台仪器的非欧姆接触情况。

If using a separate current source and voltmeter to make low resistance measurements, each instrument must be checked for non-ohmic contacts.

该仪器属于非接触式，使用聚焦的激光光束与被测表面相互作用所反馈的信息来进行表面形貌参数的测量。

As an un-contacting system, it uses the feedback-information of the reaction of the focused laser beam and measured surface to measure the surface appearance parameters.
